2021 FurMark is one of the best tools for testing graphics card stability in Windows, the application supports the OpenGL library and uses special display algorithms to test the stability of the graphics card, it is known that downloading FurMark for PC is very easy to use.
The program includes a number of useful options, as we can adjust the screen size, and choose one of the available graphics test modes. When testing a graphics card, the software displays the minimum, average, and maximum frame rate (FPS). In addition, it monitors the graphics card temperature in real time and accurately displays the GPU and clock speed. FurMark can load graphics heavily with 3D calculations, so if the graphics card is found to be defective, errors will appear on the screen in the form of texture distortions in the image.
