GPU Caps Viewer is an OpenGL tool that tests the performance of your graphics card and shows you all kinds of details about it.
The program provides information about the graphics adapter, drivers, dedicated memory, or GPU (graphics processing unit) temperature. In addition, it also shows general information about the system, and allows us to test its performance.
Regarding OpenGL, GPU Caps Viewer shows the capabilities of our card: version, texture units, supported extensions, etc.
Finally, it is also interesting to note that GPU Caps Viewer includes a system through which we can collaborate (whenever we want, of course) with graphics developers by validating our graphics card.
