The driver-level functioning of RivaTuner includes changing the settings via the registry and reading the information directly from the graphics hardware. RivaTuner works in two modes – tweaking graphics at driver level as well as low level. Also, it allows users to perform low-level hardware monitoring. Direct3D is a Windows-based Graphics API that renders 3D graphics in applications and OpenGL is an API rendering 2D and 3D vector graphics. With RivaTuner, users can tweak the application programming interfaces such as Direct3D and OpenGL. Whether your GPU cost $150, $400, or even $500, you can overclock it! The same would applie to both cheap and expensive CPUs, but RivaTuner only focuses on GPU performance. Importantly, RivaTuner works with GPUs of all price ranges.

It is compatible with most series of Windows OS, including Windows 2000, Windows 2003, Windows XP, Windows Vistas, Windows 7, Windows 8 and Windows 10. It supports GPU (Graphics Processing Unit) based display adapters of several ATI graphics processors like ATI RADEON 8500, etc. It was initially developed for the NVIDIA video cards. RivaTuner is a freeware software tool programmed to make computing devices run faster than their original configuration. The freeware program was last updated in 2009. RivaTuner tool is used to improve PC game performance, on-screen monitor system, overclock the graphics card, etc. The software has a graphical interface that allows users to tweak certain driver-levels, as such, that it has gained fame, especially among gamers. Overclocking is the practice of increasing a component’s clock rate more than certified by the manufacturer.

RivaTuner is one of the most commonly used tools for overclocking.
