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.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
