FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that’s why FurMark is also a perfect stability and stress test tool (also called GPU burner) for the graphics card.
The benchmark offers several options allowing the user to tweak the rendering: fullscreen / windowed mode, MSAA selection, window size, duration.
This benchmark requires an OpenGL 2.0 compliant graphics card: NVIDIA GeForce 5/6/7/8 (and higher), AMD/ATI Radeon 9600 (and higher) or a S3 Graphics Chrome 400 series with the latest graphics drivers and Windows XP / Vista 32-bit.
