Workloads

The workloads in this product include:

1. Theoretical shader performance measurements
2. Practical shader performance measurements
3. Practical game performance measurements

Of these, tests 1 & 2 are represented as high-level description of shaders and parameters and test 3 is a description for creating a Direct3D trace from Futuremark’s desktop benchmark 3DMark.

Technical Information

• The configurable shader in workloads 1 & 2 is based on the Schlick shading model, which can be considered a Bidirectional Reflectance Distribution Function (BRDF) factorization approximation.
• Theoretical performance measurements will be made with simple vertex and simple pixel shaders, trying to maximize the performance.
• The shader will use a simple quad as a test object. The level of tessellation is planned to be configurable. Most of the shader code can be chosen to be executed in either vertex of pixel shader.
• The test scene will contain two objects with varying (configurable) amount of overlap. This will measure performance of depth solutions such as tiled architecture and hierarchical Z buffer.
• Vertex skinning has been included.
• For the practical game performance measurement, a tracing tool and 3DMark05 Professional version is needed.
