I updated from Windows 8 to Windows 8.1 and now 3DMark refuses to start. Incompatible?
No, 3DMark is compatible with Windows 8.1. The problem is that Windows 8.1 update removes the required Futuremark SystemInfo service from Windows and 3DMark cannot start the required service on startup. Please uninstall Futuremark SystemInfo from programs, then either reinstall 3DMark or install the latest stand-alone Futuremark SystemInfo (available here) and it will correct the issue.
I'm experiencing total system hang during a test or test exits with "process exited unexpectedly" error.
Most common cause for this is that either you system does not support High Precision Event Timer (HPET) or it is disabled in BIOS. You can test this by going to help tab and unticking "SystemInfo Hardware Monitoring". If the problem goes away, check if your motherboard BIOS has the option to enable HPET and enable it. If problem persists even with HPET enabled when you re-enable Hardware Monitoring, contact Futuremark Support and include full details about your hardware configuration.
Alternatively we have reproduced this error on systems with Lucid Virtu MVP 2.0 software enabled. It appears that Virtu MVP and most recent drivers from graphics card vendors can crash in 3DMark and this is the error you'll then see. To solve the issue, disable Virtual Vsync and Hyperformance in Virtu MVP settings or uninstall Virtu MVP.
Finally, if you are seeing "process exited unexpectedly", it could also be caused by lack of memory. Most commonly this is seen with Fire Strike on systems with only 2GB of RAM and no dedicated video memory. Fire Strike requires at least 2GB RAM and 1GB video RAM to run while Fire Strike Extreme requires 4GB RAM, 64bit operating system and 1.5GB video RAM. Systems with 2GB or less but no dedicated video memory are unable to run Fire Strike and systems with 4GB or less and no dedicated video memory are unable to run Fire Strike Extreme. Such systems crash on loading with "process exited unexpectedly". When doing a complete run with all tests, you will still get Ice Storm and Cloud Gate test scores after you close the error message.
I'm having problems starting the Steam version of 3DMark
Verify that all pre-requisites installed properly. 3DMark requires that Futuremark SystemInfo and NET Framework 4.5 are properly installed and normally Steam version of 3DMark installs these. However, if installation fails, 3DMark can then fail to start. If problem persists, contact Futuremark Support and include details about your hardware configuration and background applications you have running on the system.
I'm getting "GUI Has Stopped Working" immediately when I try to start 3DMark
This can occur if Futuremark SystemInfo is not properly installed or the system service is disabled. Uninstall and then reinstall Futuremark SystemInfo (Latest stand-alone installer is available here) and verify from Windows Services that Futuremark SystemInfo Service is not set to be disabled.
I'm having problems viewing results online ("View result online" doesn't do anything)
Check if you have antivirus software that blocks 3DMark from opening a browser. Reportedly at least Avira AV will prevent 3DMark from opening the default browser to display results. Temporarily disable such software and/or contact your security software support and ask for assistance. If this is not the cause, make sure you actually have a default browser set in Windows.
I'm having problems getting Hardware Monitoring to show temperatures and clock speeds (Advanced Edition)
This is a known issue with 3DMark v1.1 and is corrected with the v1.2.250 update which features a complete re-write of this functionality - install latest update to 3DMark. Note that if you are seeing some but not all of the data, this is normal - not all hardware configurations provide all different forms of monitoring data.
I'm having problems with SLI/Crossfire performance, I'm running Windows 7 and I have two video cards
Microsoft recently pushed an update to Windows 7 through Windows Update that affected performance in 3DMark when SLI/Crossfire was used. The update in question is KB 2670838. The issue was corrected in 3DMark v1.1 so verify that your benchmark is up to date.
I'm having problems with SLI/Crossfire performance and I have more than two video cards
Multi-GPU issues were resolved in 3DMark v1.1 update - verify that your benchmark is up to date. Only remaining known issue is that Crossfire configurations with four GPUs sometimes exhibit poor performance in the combined test. AMD has been notified and they are investigating.
Note that Multi-GPU configurations with more than two cards use up additional video memory due to resources that have to be duplicated on every card. For Fire Strike we recommend at least 1.5GB per card for 3-4x SLI/Crossfire and Fire Strike Extreme we recommend 2GB or more per card. The tests should run even when using cards with less memory but there will be a performance penalty as video driver has to use main RAM to extend the video memory.
I'm having stability issues when running loop testing and get error about display resolution changing
While the loop tickbox in Custom tab does disable most of the anti-tampering checks, when loop testing for hours in full screen mode, the run can be interrupted if some background application draws a popup or task bar notification as it causes a switch back to the desktop view. 3DMark cannot recover from such display mode change.
For very long stability stress tests we recommend testing using the windowed mode. Windowed mode is not interrupted by task bar popups or other interrupts from background applications, only actual driver crashes or general system instability will stop the test. When looping all parts of a test, there are loading screens with light load between each part. For maximum load set the stress test loop to loop a single part of a test - Fire Strike Game Test 1, for example - and the loop will be continous without loading screens. Note that when looping, the run will never produce a score.
Is 3DMark compatible with Windows 8 / 8.1?
Yes, 3DMark is compatible with Windows 8 and 8.1
What version of DirectX does 3DMark use?
Every test in 3DMark uses a DirectX 11 engine. We then use a DirectX 11 property called Direct3D feature levels to create tests for specific versions of DirectX compatible hardware. Direct3D feature levels allow developers to use a DirectX 11 engine while still supporting existing hardware, from DirectX 9 to DirectX 11, from lightweight tablets to high-end desktops.
Ice Storm uses a DirectX 11 engine limited to Direct3D feature level 9_1, while Cloud Gate uses a DirectX 11 engine limited to Direct3D feature level 10_0. Fire Strike uses a multi-threaded DirectX 11 engine.
Does 3DMark use DirectX 11.1?
Yes, but only in a minor way and with a fallback for DirectX 11 to ensure compatibility with the widest range of hardware and to ensure that all tests work with Windows Vista and Windows 7 as well as Windows 8.
DirectX 11.1 API features were evaluated and those that could be utilized to accelerate the rendering techniques in the tests designed to run on DirectX 11.0 were used.
Discard resources and resource views
In cases where subsequent Direct3D draw calls will overwrite the entire resource or resource view and the application knows this, but it is not possible for the display driver to deduce it, a discard call is made to help the driver in optimizing resource usage. If DirectX 11.1 is not supported, a clear call or no call at all is made instead, depending on the exact situation. This DX11.1 optimization may have a performance effect with multi-GPU setups or with hardware featuring tile based rendering (sometimes found in tablets and entry level notebooks).
16 bpp texture formats
The 16 bpp texture formats supported by DirectX 11.1 are used on Ice Storm game tests to store intermediate rendering results during post processing steps. If support for those formats is not found, 32 bpp formats are used instead. This optimization gives a noticeable performance effect on hardware for which the Ice Storm tests provide a suitable benchmark workload (tablets, entry level notebooks).
There are no visual differences between the tests when using DX11 or DX11.1 in 3DMark and the practical performance difference from these optimizations is limited to Ice Storm on very low end Windows hardware, and on Windows RT.
Does 3DMark use DirectX 11.2?
If Ice Storm is a DirectX 9 test, why doesn't 3DMark work on Windows XP?
Every test in 3DMark uses a DirectX 11 engine, including Ice Storm, our new 3DMark test for DirectX 9 compatible mobile devices. Ice Storm uses a DirectX 11 engine limited to Direct3D feature level 9_1. 3DMark will not run on Windows XP PCs, since DirectX 11 is not available on Windows XP.
What is the difference between 3DMark Fire Strike and 3DMark 11?
3DMark 11 is our first DirectX 11 benchmark, released in December 2010. 3DMark Fire Strike, released in February 2013, is our second generation DirectX 11 benchmark and is the more modern and demanding of the two.
Default rendering resolution
- 3DMark 11 - 1280x720 (720p)
- 3DMark Fire Strike - 1920x1080 (1080p)
Extreme preset rendering resolution
- 3DMark 11 -1920x1080 (1080p)
- 3DMark Fire Strike - 2560x1440 (1440p)
While 3DMark 11's Entry preset can prove useful for testing entry-level hardware, in most cases we recommend using 3DMark Fire Strike for testing DirectX 11 based systems. Scores from 3DMark 11 and 3DMark Fire Strike cannot be directly compared.
What is the difference between 3DMark Fire Strike and 3DMark Fire Strike Extreme
3DMark Fire Strike Extreme is a slightly modified version of 3DMark Fire Strike and is designed for high end multi-GPU (SLI/Crossfire) systems and future hardware generations. In addition to the higher rendering resolution, additional visual quality improvements increase the rendering load to ensure accurate performance measurements for truly extreme hardware setups.
Scores from 3DMark Fire Strike and Fire Strike Extreme should not be compared to each other - they are separate tests with their own scores, even if they share the same benchmark scenes.
What is the difference between 3DMark Cloud Gate and 3DMark Vantage?
3DMark Vantage and 3DMark Cloud Gate are both benchmarks for DirectX 10 capable hardware. The difference is in the engine powering each benchmark. 3DMark Vantage, released in April 2008, uses a DirectX 10 engine. In comparison, 3DMark Cloud Gate uses a DirectX 11 engine limited to Direct3D feature level 10_0. Using Direct3D feature levels is the modern approach to game engine design as it allows developers to use a DirectX 11 engine and still support older generation hardware all the way down to DirectX 9 level models.
We recommend using 3DMark Cloud Gate for testing DirectX 10 based systems. Scores from 3DMark Vantage and 3DMark Cloud Gate cannot be directly compared.
What is the difference between 3DMark Ice Storm and 3DMark06?
3DMark06 and 3DMark Ice Storm are both benchmarks for DirectX 9 compatible hardware, however, they use different engines and target different types of hardware.
- 3DMark06 - DirectX 9
- 3DMark Ice Storm - DirectX 11 limited to Direct3D feature level 9_1
- 3DMark06 - powerful desktop gaming PCs (in 2006)
- 3DMark Ice Storm - powerful mobile devices (in 2013)
For testing modern gaming PCs we recommend using 3DMark Cloud Gate or 3DMark Fire Strike rather than 3DMark06, since such systems will almost certainly support DirectX 10 or DirectX 11. 3DMark Ice Storm is the ideal modern benchmark for DirectX 9 compatible mobile devices such as tablets, netbooks, ultra-portable notebooks and entry-level PCs. Scores from 3DMark06 and 3DMark Ice Storm cannot be directly compared.
My benchmark score from 3DMark Ice Storm fluctuates wildly between runs. Is something wrong?
3DMark Ice Storm was designed for mobile devices such as tablets and netbooks, so is a very lightweight test for any modern high end gaming PC. On high end systems the framerate can be over 1000 frames per second. On such systems 3DMark Ice Storm really isn't the correct test to run as even a tiny variation in the time it takes to render each frame can cause major changes in the framerate, leading to major fluctuation in the final score. As a rule of thumb, if you score more than 40 000 points in 3DMark Ice Storm, your system is "too good" for the test and you should instead use 3DMark Cloud Gate or 3DMark Fire Strike to benchmark your system.
Also note that some power saving features may trigger when running Ice Storm. The benchmark load is so light that the video card may decide that lower operating frequency is fine and this may cause the score to fluctuate. If you are seeking the highest possible score in this test on a high end system, you may need to explicitly force your video card to operate in "high power" mode through video driver settings.
On very fast setups and on most multi-GPU (SLI/Crossfire) configurations, 3DMark Cloud Gate will also end up being limited by your processor and you will see similar (if smaller) effect. You should always use the benchmark most appropriate for the hardware you are benchmarking - the performance range of hardware that can be benchmarked using 3DMark is simply far too wide to cover it all with just a single test and that is the reason why 3DMark includes three different tests and the extreme preset for Fire Strike to cover all cases - even situations involving heavily overclocked processors and multi-GPU SLI/Crossfire setups cooled using liquid nitrogen or liquid helium.
I changed my desktop resolution and my scores changed slightly. Why?
3DMark works differently from 3DMark 11 to tackle the issue of different display sizes and resolutions. 3DMark always renders the tests internally at the resolution specified for each test ("offscreen rendering") and then scales the image to your desktop resolution before displaying it, preserving the aspect ratio (applying letterboxing if the desktop aspect ratio is not 16:9).
Internal rendering resolutions of 3DMark tests
- 3DMark Ice Storm - 1280x720 (720p)
- 3DMark Cloud Gate - 1280x720 (720p)
- 3DMark Fire Strike - 1920x1080 (1080p)
- 3DMark Fire Strike Extreme - 2560x1440 (1440p)
If you alter your desktop resolution, you will also alter the target resolution for the final image scaling. On modern hardware, display scaling is almost "free" and in general the scores are comparable no matter what desktop resolution you use. However, when a test becomes limited by the CPU and framerates get very high (Ice Storm on almost all desktop hardware, Cloud Gate on high end hardware), there can be a small impact to the score from image scaling. If you seek to obtain the absolutely highest score from a test (for overclocking contest purposes, for example), setting the desktop resolution to match the internal rendering resolution of the test you are running may provide a very slight increase to your score.
Help tab includes an option to change between letterboxed and stretched scaling. This can be used, for example, to scale the image to fill a triple monitor Eyefinity setup. Aspect ratio is not preserved when stretched is selected. Note that this does not change the workload - it is still rendered in the internal rendering resolution, just scaled differently
Custom tab (Professional and Advanced Edition) allows you to alter the internal rendering resolution for a custom run. The usual caveat applies that custom runs do not produce an overall score and sub-scores cannot be directly compared to scores obtained with default settings.
Why does the benchmark run so slowly? Why are my framerates so low?
Benchmarks are designed to place a heavy load on your PC to identify the weak points and bottlenecks in your hardware. It is sometimes the case that only small differences in visual quality can be seen from very large increases in the amount of processing required.
Why are there MSI and Galaxy/KFA2 logos in the benchmark demos?
The logo placements are a special sponsorship arrangement between those companies and Futuremark. Advertising placements ensure that we can offer the free 3DMark Basic Edition alongside the paid editions.
I have issues with the SystemInfo scan at the start with 3DMark - how do I fix this?
First make sure you have the latest update to SystemInfo installed.
Alternatively you can try disabling SystemInfo scan by unticking "Scan SystemInfo" in the Help tab but do note that any results from such a run cannot validated as they are missing information on the hardware configuration.
If you are getting a complete system hang during SystemInfo scan, ensure that HPET is enabled in your BIOS settings. SystemInfo Hardware Monitoring requires HPET (High Precision Event Timer) to function. Also ensure that your motherboard BIOS is up to date.
I'm using Windows Vista and I can't get 3DMark to start?
This is most likely due to a missing Windows update that is required for DirectX 11 applications to run on Windows Vista. Download and install the Platform Update for Windows Vista from Microsoft.
3DMark fails to load on my phone - it just stops during loading or loads the first test and then exits. Why?
The most likely cause is lack of memory. First, verify that your device has 1 GB (1024 MB) memory to meet the minimum requirements. Second, note that any applications that are running in the background also consume memory. We recommend closing all background apps before running the tests as such programs always consume some resources and may influence your benchmark score negatively.
3DMark for Android v1.0.1 update includes changes that should resolve this issue for any 1 GB device models. Verify that you have the updated version. Devices with less than 1 GB are officially unsupported but may be able to run the tests if you untick "run demo" in the settings.
3DMark returns to the menu after the Ice Storm demo, and I don't get a score.
3DMark for Android v1.0.1 resolves this issue. Check that you are running the latest version, then try again.
3DMark crashes on my Android device. Help!
We've tried to flag all the incompatible devices on the Google Play store but as there are so many devices and variants, we may have missed some. Please help us improve the accuracy of our list by telling us about your incompatible device.
The most common compatibility problem is with devices, such as the Samsung Galaxy Nexus or Samsung Galaxy Tab 2, that have the TI OMAP 4430 or TI OMAP 4460 chipset. We don't currently have a workaround, unfortunately, but now that 3DMark is publicly available we hope that the manufacturers and operators offering devices with these chips will notice the compatibility issues and work with us to fix them. Note that unticking "run demo" in the settings may allow you to complete a run on OMAP-based devices but there will be graphics corruption in the physics test.
For all other devices and any other crash issues, please post on our support pages including as much detail about the problem and your device as possible.
The benchmark stopped running in the middle of the test. Why?
If you are using a compatible device, make sure that all other apps running in the background have been closed. You may also want to temporarily disable notifications as the benchmark run will end prematurely if it is interrupted by an external application.
I updated my Nexus 7 (2012) operating system to Android 4.3 and now 3DMark fails immediately at the start of a benchmark run. Help!
This compatibility issue was fixed in 3DMark 1.0.3-1138. Check that you are running the latest version, then try again. A small number of users reported that the update doesn't work right away. If this happens to you, just delete 3DMark from your device and then reinstall it from Google Play.
Why doesn't 3DMark recognise my 2nd generation (2013 model) Nexus 7?
3DMark for Android v1.1.0-1179 resolves this issue. Check that you are running the latest version, then try again.
What are the minimum hardware requirements for 3DMark on Android?
OS: Android 3.1 or laterMemory: 1 GBGraphics: OpenGL ES 2.0 compatibleStorage: 300 MB
Where can I find more technical detail about the tests?
Our 3DMark technical guide contains detailed descriptions of the tests and an explanation of how scores are calculated. The guide covers all platforms, including Android.
3DMark says I have a Mystery Machine. What does that mean?
This message simply means that we haven't mapped your device details in our database yet. There are more than a thousand compatible Android devices and we are working hard to map and verify them all.
Even if your device is not identified, your benchmark score is still perfectly valid for making comparisons. The model and hardware details won't be visible in the Device Channel until we update our device database. You can get the latest list by completely closing 3DMark on your device, then restarting 3DMark. We refresh the database every hour.
If you have a brand new device model, feel free to report the problem and include a link to a website detailing the hardware specs of your device.
Some of the hardware detail data shown on 3DMark for my device is incorrect.
We do our best to verify all data. There is a button at the bottom of the "My Device" page where you can report errors you have spotted to us for fixing. Please describe what you believe is incorrect.
Also note that some popular phone models can have very different hardware depending on where and when they were bought, even if they share the same model name. You may want to first verify your exact model so that you are absolutely certain the data is in error.
If you notice that we have mis-mapped a device (i.e. the data fits to another model of the same device but not yours), do mention that when reporting the issue.
My 3DMark scores seem to vary wildly between runs. Can I trust these results?
Some high-performance devices use aggressive thermal throttling to control the temperatures of the processors inside the device. As the device heats up it intentionally slows the processor to avoid overheating, which in turn leads to lower performance scores on successive runs.
To reduce this effect, we recommended waiting 15 minutes between runs to allow the device to cool down. You should also unplug the device during testing as the battery charging circuitry also generates heat.
You can also try to keep the device cool by running the test in a cold environment. We tested several devices in a freezer during our own testing!
Measuring the effects of thermal throttling is another interesting way of using 3DMark to compare the performance of different devices.
What's going on with the Device Channel score lists? I ran the test and scored better but my score is not there.
Device Channel is not a "Hall of Fame". Android version of 3DMark has far too little information about the hardware and settings of the phone to make any determination if the run is actually legitimate so we actively chose not to do any kind of high score lists. "My Device" shows your personal top scores and you can share results using social networks but there is no functionality to "compete" with high benchmark scores.
The Device Channel scores are averages of all recorded runs from users of that specific phone model, with unusually high or low results filtered out and with a minimum threshold of results before a device can appear on the list. Most popular models have thousands of runs so even if you do a super-overclocked run, the average most likely won't change - it's just one run among thousands and most likely isn't even counted in the average due to being an outlier result. The goal is to show how devices typically perform with stock settings.
I'm running a custom ROM and my device isn't recognized (or it is recognized incorrectly). Why?
Most results with custom ROMs simply do not have required model and manufacturer information present so we cannot tell what kind of hardware you have. 3DMark on mobile devices currently does not do any kind of hardware detection - it just reads the manufacturer and model information. This is also the reason why any overclocks do not show in "My device" and processor information only shows the possible maximum known clock speed for the processor model found in the device. Sometimes manufacturers limit the default clock speed to improve battery life and reduce heat.
3DMark is simply not designed to extract this information from the hardware. This also means that if you are using a custom ROM that has a "fake" device string, 3DMark can show incorrect information. Most common case seems to be that some Chinese Android tablets have ROMs available that claim that they are "gt-i9300" which is Samsung Galaxy S III (Exynos 4 Quad). Currently there is no workaround for this - if your device manufacturer / model information is incomplete or wrong, 3DMark can't identify it. Same is also true for various "knockoff" phones that may physically appear to look like a well-known model (Samsung Galaxy S III and S IV seems to be the most common target at the moment) but the actual internal hardware of the device is completely different. If it's not a genuine device, 3DMark most likely won't identify it at all.
In all these cases the benchmark score is still valid - benchmark workloads do not know which device you are using and the performance measured is still accurate, so the issue is mostly cosmetic.
I've reported my device as unknown and it's been days/weeks and it is still not showing. Why?
There is a massive number of Android devices out there and while we are working on getting as many of them mapped properly as possible, it is slow work. All the prepared data we had available before launch is already mapped to devices and all the remaining unidentified devices take a lot of manual work to gather the required data so it is taking time.
Some devices are so obscure that we cannot tell from the model information with any certainty as to which exact model the device is, or we cannot find reliable hardware configuration information online for the device (most commonly seen with obscure variants of Android tablets where technical data is simply not around, or only available in a foreign language). If you want to assist providing data about your device, please post on our support pages and include as much detail as possible and specify the the manufacturer/model strings if you know them.
"Ouch! Something has gone wrong.", "An unknown error occurred." or "An error occurred while running benchmark."
These are generic errors that comes up when something unexpected happens. These errors should include a full technical error message about the issue. If you have no idea what could have caused the problem, contact Futuremark Support with the full error message for further assistance.
"Window focus lost during benchmark run."
This error occurs if some background application interferes with 3DMark and tries to draw a popup window, an overlay or otherwise switches the window focus from full screen 3DMark view during a benchmark run. In such cases the score would no longer be accurate so the test is aborted.
Most common culprits causing this error include various instant messaging and email applications that give popups when a new message arrives. Turn off such applications and try again. In general it is recommended to close any unneeded background applications before benchmarking a system to ensure that all system resources are available during the test.
"Connecting to www.3DMark.com failed. Are you connected to the Internet?"
Online result validation and result viewing online both require internet connection. This error usually means that you are not connected to the internet or you cannot reach 3DMark.com server at all. 3DMark.com itself is almost certainly still online - you just can't reach it.
"Could not connect online."
A subtly different problem - you have an internet connection and 3DMark.com can be reached but for some reason the server is down. Usually this error is our fault and our administrators are already busy restoring service. If the problem persists for longer, contact Futuremark Support to ensure that we're aware of the problem.
"Online result validation failed."
Something is wrong with the 3DMark.com result validation service. If there is nothing out of the ordinary with your benchmark run and the problem persists, contact Futuremark Support with details about your hardware and save a copy of your result to a file (if using Professiona or Advanced Edition) in case it is needed to investigate the problem.
"Checking DirectX compatibility failed."
This is a highly unusual error message that would imply that DirectX is not properly installed or it simply refuses to provide information on the hardware available. Contact Futuremark Support with full details about your hardware configuration and your operating system for further assistance.
"DirectX 9/10/11 compatible hardware required."
A DirectX 9 compatible video card is the minimum for starting 3DMark and it is required for the Ice Storm test. There is a further requirement of DirectX 10 capable card for Cloud Gate and DirectX 11 capable card for Fire Strike tests. If you know for a fact that you have the proper hardware and are still getting this error, it may be caused by corrupt video driver installation. Try completely removing your video drivers with a third party driver cleaning utility, then reinstall the latest available drivers and try again. Contact Futuremark Support with details about your hardware (including DXDIAG output text file) if you cannot resolve the issue and think you are getting this message in error.
"Loading result failed."
There is something wrong with the result file you tried to load. If you are certain that you have not tampered with the file, contact Futuremark Support and ensure you can provide the result file for analysis.
"Saving result failed." or "Exporting results to XML failed." (Professional Edition only)
These errors usually indicate that your disk is full or you do not have permission to write to the folder where you are trying to save or export a result. Correct the problem and try again.
"Test run was cancelled by user."
Yes, pressing ESC cancels the test. This is not really an error, more of a notification why the test ended.
"Invalid upgrade key"
First ensure that the key you are inputting is in the form of
YYYYY sections are alphanumeric strings that contain numbers (0-9) and letters. Note that letters I and O will never show up in this part of the key. Anything resembling an I is number 1 (one) and O is always 0 (zero).
If you still can't get your key to work, please send us an email and include a photo or scan of the key if it was printed on paper and tell us where you got it so we can assist further.
"Registering a professional licence requires an internet connection."
Connect your system to internet to resolve this error. If you are using 3DMark Professional Edition in an environment where no network connection is available, contact Futuremark Professional Support for further assistance.
"This program requires Steam. Please restart Steam client and try again."
This error can come up only with the Steam version of 3DMark. Something is wrong with Steam on your system. For whatever reason, 3DMark cannot start Steam API and communicate with Steam client. If verifying local files does not solve this problem and it happens on all Steam editions (also 32bit), contact Futuremark Support or use a stand-alone version of 3DMark.
Updated August 21, 2013
