When using Intel GPA, using the latest version of the graphics drivers ensures that you are getting the most accurate metrics when analyzing and optimizing your game or graphic-intensive application.
A top-down approach to analysis and optimization suggests that first you have to determine whether your performance issues are with the CPU or the GPU. Understanding your performance issues at this highest level is extremely important. Otherwise, you could spend a lot of time optimizing parts of your game that end up being secondary to much larger performance issues.
The Simple Pixel Shader override mode replaces every pixel shader with one that writes a constant color to the render target.
If the frame rate shows a large increase with this override enabled, this is an indicator that the performance slowdown is due to pixel shader computation and/or texture performance. In this case, you should inspect your scene with the Graphics Frame Analyzer to identify and rework expensive pixel shaders to improve scene rendering performance.
While profiling DirectX 9, 10, or 11 frames, you can:
To save the Pixel History tab image to your system:
Select the render target from the Render Target Thumbnail List.
Click the image in the Render Target View and go to the Pixel History tab.
Right-click the Pixel History Render Target View image and select Save...
This section lists solutions for some of the known issues you may encounter when working with the Intel® GPA.
With the System Analyzer, you can view and analyze custom metrics of your profiled graphics application.
Follow the procedure described below to analyze your custom metrics.
