    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.

    Simple Pixel Shader

    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.
