FurMark: Direct Download Link

FurMark is an OpenGL-based GPU stress test utility (also called GPU burn-in test). It makes it possible to push the GPU to the max in order to test the stability of the graphics card (and the PSU too!) leading to maximal GPU and VRM temperatures.

That’s why FurMark is often used by overclockers and graphics cards fanatics to validate an overclocking, to check the cooling system or to detect a weak point in the graphics card.

What is FurMark?

FurMark is a VGA stress test and GPU burn-in test as well as an OpenGL Benchmark. The benchmark offers several options allowing the user to tweak the rendering: fullscreen / windowed mode, MSAA selection, window size, duration.

The benchmark also includes a GPU Burner mode (stability test). The stresses can be customized using the command line parameters of FurMark. 


FurMark 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.

How it works?

FurMark is simple to use and is free.

The GPU temperature can be monitored by watching the second graph (the green line). FurMark reveals the temperature very quickly: within 10 seconds of launch, the GPU temperature reaches 85°C! The maximum GPU temperature is reached within 2 minutes.

If you want to record your benchmark results, just press ALT-F and enter your name. At the end of the test, a score is displayed: this score represents the mean value of FPS (frames per second) during all benchmarks.

If you already have a previous version of FurMark, make sure to update it before proceeding.

How to use FurMark?

Open FurMark, and you’ll see various settings you can play around with.

1. You can select from three preset graphics modes: 780p, 1080p, or 4K resolution (3840×2160). You can also tweak the settings manually to get the desired resolution and other details.

You can change the benchmark duration to 10 minutes or 30 minutes. The default setting is 10 minutes. 

2. You can also change the type of benchmark, either a standard benchmark or an extreme stress test that pushes your GPU to its limits by using more than one OpenGL window at once.

The default setting is standard benchmark, which is recommended unless you wish to push your GPU beyond its limits.

3. Click the “Benchmark” tab and check the “Stability Test” box. This will allow FurMark to run for as long as you like without crashing or overheating your system. Click OK to close the window when done.

4. Click the “Benchmark” button to start the benchmarking process. Your GPU will heat up as the test progresses—if it gets too hot, the benchmark will stop itself automatically. I

f you have an NVIDIA GPU, a window will pop up showing how well your card performs with different games at different resolutions and settings.

5. After the benchmark finishes, click “Quit” and close FurMark if you want to end the stress test as well. You can also click “Screenshot” to get a screenshot of your GPU performance statistics or click “Save Report” to save them to a text file for later reference.
