In the Experiments pane, you can isolate potential performance bottlenecks in your application by modifying render states of Graphics API.

NOTE:

You can only perform experiments if metrics data is available for your target system; otherwise, the Experiments pane is hidden from view.

Icon	Description	DX11 Frame/Stream (Windows)	DX12 Frame (Legacy) Available in Extended Profile Mode (Windows)	DX12 Frame/Stream (Windows)	Vulkan Frame/Stream (Windows)	OpenGL Frame (Ubuntu)
	2x2 Textures Identifies potential performance bottlenecks caused by texture maps used in your application. All sampling textures for a scene are replaced with 2x2 texture containing four different colors.	Yes	Yes	Yes	Yes	Yes
	Simple Pixel/Fragment Shader Replaces every pixel/fragment shader with the pixel/fragment shader that writes a constant color to all render targets.	Yes	Yes	Yes	Yes	Yes
	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.	Yes	Yes	Yes	No	Yes
	Disable Event(s) Keeps the selected events from being rendered. This experiment can help you test scene efficiency.	Yes	Yes	Yes	Yes	Yes
	Shading Rate Adjusts the shading rate for the selected resource, which can help identify objects that could be rendered with less quality without noticeable visual impact.	No	Yes	Yes	No	No
