The metric Pixel Shader Duration represents an approximation of the total GPU time spent executing pixel shader code.
- If Pixel Shader Duration is 50,000 it means that GPU spends around 50 milliseconds to execute pixel shaders for the selected ergs.
- If Pixel Shader Duration is 0 it means that time spent in pixel shaders for selected ergs is very small.
Examine the Pixel Shader Duration time versus the GPU Duration; when Pixel Shader Duration is high you may improve overall rendering performance by optimizing your pixel shader code.
Check the Shaders Tab in the Intel® GPA Frame Analyzer and examine pixel shader code to see if optimizations are possible. Refer to the HDG DirectX Developers Guide to find advice for pixel shader optimizations.
