RivaTuner is one of the most powerful tweaking utilities for Nvidia display adapters running under Windows 98 / Windows 98 SE / Windows ME / Windows 2000 and Windows XP. The purpose of this utility is to give you access to all the undocumented features of the Detonator drivers. All versions of the 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).

Minor bugfixes: Fixed crystal clock frequency detection for nForce based boards. Revised PLL dividers calculation algorithm. The maximum VCO frequency control, which has been introduced in the previous version, could cause RivaTuner to generate invalid PLL dividers and hang in low clock frequency generation accuracy mode. This problem appeared on the clock frequencies below 128MHz (mainly on TNT/TNT2 and GeForce256 based boards). Now RivaTuner doesn't control the maximum internal PLL frequency when the PLL post divider is frozen. Fixed the maximum VCO frequency for NV17 based boards. What's new: Added VCO frequency related info to the 'NVIDIA specific display adapter info' diagnostic report category. Now RivaTuner can dump the maximum internal PLL frequency, dump and check internal frequencies for core and memory PLLs. Added undocumented ShowRoundedClks registry entry, which allows the power users to control RivaTuner's clock frequency rounding behavior. Added undocumented SetDeviceGammaRampColorControl registry entry, which allows to work around corrupted color correction startup routine in the Detonator drivers (e.g. on GeForce2 MX with Detonator 21.xx or on GeFroce4 with Detonator 27.xx) and set gamma ramp bypassing the drivers. Added hotkey manager. Now you can associate the hotkeys with the launcher's items and use the launcher's features (e.g. change a color scheme) without leaving a game and switching to RivaTuner. Added DirectX 8.1 specific info to the 'IDirect3D8 HAL capabilities' diagnostic report category. Context help updated. FAQ updated.
