Pane: Experiments

In the
pane, you can isolate potential performance bottlenecks in your application by modifying render states within the graphics driver.
You can only perform experiments if metrics data is available for your target system; otherwise, the
pane is hidden from view.
Simple Pixel/Fragment Shader
Replaces every pixel/fragment shader with the fragment shader that writes a constant color to all render targets.
1x1 Scissor Rect
Bypasses pixel processing from the rendering pipeline: if the frame rate does not increase when this experiment is enabled, then a complex geometry or vertex shader is a bottleneck.
Disable Event(s)
Keeps the selected events from being rendered. This experiment can help you test scene efficiency.

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.
