1x1 Scissor Rect

The
1x1 Scissor Rect
 override mode cuts pixel processing from a pipeline. If the frame rate does not increase after enabling this override, then a complex geometry or vertex shader is a bottleneck. In this case, you can use the
Show Wireframe
 override mode to check whether the geometry is complex. If the geometry is not complex, then the vertex shader is the bottleneck.
However, the effect of this override mode is driver/graphics hardware vendor specific and depends upon whether scissoring on your device occurs prior to or after the pixel shader stage.

Product and Performance Information

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.
