NVTweak (Formerly Coolbits) provides some extra quality tweaks that both the default NVIDIA tray icon and control panel are lacking. I especially wanted to be able to select more Antialiasing modes, as well as OpenGL and Direct3D options right from the tray icon. Also, the utility is able to run automatically at startup thus making it a bit easier to change my settings before playing a game or running a benchmark. This program requires .NET Framework 2.0 to support a broader range of systems.

NVTweak will unlock many extra options in the NVIDIA control panel/driver, including but not limited to - Overclocking, AGP & Hardware settings, Fan control, Temperature settings, Debugging, Twin View, Video Mixing Renderer, OpenGL 2.0 support, 3D viewer

IMPORTANT!
This tweak is intended for use with GeForce/Quadro cards and ForceWare 55.xx - 9x.xx 3D Stereo drivers. NVTweak is not fully compatible with Windows 98/Me or driver versions older than 55.xx. If you do happen to run this tweak with older software, you could get errors at startup! To enable full compatibility, you will need to disable the options that are causing issues with your current setup.

NVTweak allows you to operate a graphics card out of normal specifications by overclocking and/or modifying how the driver operates. You should always use the overclocking utility with extreme care! I will not be held responsible for any damage that may result from the improper use of this program.
