Disable Alpha Test Windows

Use the
Disable Alpha Test
override mode to understand the performance impact of testing each pixel’s alpha component. Performance may increase because at least the same number of pixels will be rendered, but may decrease because alpha blending may be enabled to blend pixels that were rejected by the alpha test.
NOTE
The
Disable Alpha Test
override mode might cause rendering artifacts to appear, especially if the scene uses textures or other techniques that would not be rendered due to failing the alpha test
This override is available only for Microsoft DirectX* 9. For Microsoft DirectX* 10 and Microsoft DirectX* 11 applications you should use the
Simple Pixel Shader
feature to get similar results.

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.
