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. Detected GPUs are displayed in the main window, supporting a maximum of four. You can choose to run several predefined test cases which involve a simple Burn-in test, Burn-in benchmark with higher resolution that runs for 15 minutes, and two more presets. The application's rendering algorithm is highly multipass (100 passes) and each pass (or layer) uses a GLSL (OpenGL Shading Language) vertex / pixel shader to make the hairs finer.


The startup interface allows you to tweak the benchmark features such as:

Benchmark mode or stability test mode (for overclockers)
GPU temperature monitoring and recording in a file
Fullscreen or windowed for each type of run mode
Window size selection (standard or custom)
MSAA samples selection
Benchmarking parameters: time based or frames based
