GraphicsDev_GPUPerfAPI_1140x100

GPUPerfAPI is AMD’s library for accessing GPU performance counters on ATI Radeon graphics cards. It is used by GPU PerfStudio 2 and AMD CodeXL and is also available to third party developers who wish to incorporate it within their own applications. GPUPerfAPI supports DirectX10, DirectX11, OpenGL, and OpenCL applications.
