Donuts is the graphics card testing software Furmark.

The name Donuts comes from the fact that the test screen is a circle that is constantly shaking, and Furmark is one of the most commonly used graphic card testing programs for checking the temperature, power consumption, and stability of your graphics card.

Tool Description:

Provides a wide range of testing options, such as fullscreen/windowed display modes, nine predetermined resolutions (which can also be customized), time- or frame-based testing formats, multiple multi-sampling antialiasing (MSAA), race modes, and more, and support for five languages, including Simplified Chinese.

Utility:

Originally, FurMark was designed to test the performance of a graphics card's OpenGL performance, but because it is so hot and powerful, it can be used as a burn-in program. 　

FurMark is already testing OpenGL 2.0 performance. As a result, graphics cards require an NVIDIA GeForce 5 or higher and an AMD/ATI Radeon 9600 or S3 Graphics Chrome 400 series or higher. The test offers a number of options, including fullscreen/windowed settings, MSAA options, window size, test duration, and of course, GPU stability testing (grilling).
