Guru3D has released Release Candidate 12 of RivaTuner 2.0 :
RivaTuner is the most powerful tweaking utility for NVIDIA display adapters running under Windows 98 / Windows 98 SE / Windows ME / Windows 2000 / Windows XP. The purpose of this utility is to give you access to the many undocumented features of Detonator drivers. All versions of Detonator drivers have a lot of undocumented registry entries. Some of them don’t affect anything, but there are some that are very useful. In general, they cannot give you big performance boost but they can improve image quality and solve some compatibility problems. RivaTuner will help you to change all undocumented registry entries. It supports all versions of Detonators drivers starting from Detonator 2.08 under Windows 98 / Windows 98 SE / Windows ME (Detonator 5.08 or higher under Windows 2000 / Windows XP).
Now with GeForce4 and ATI Radeon 8500/9000/9700 support !
