nHancer

nHancer is an alternate control panel for nVidia graphic cards that will allow both novice and advanced users to modify settings and performance of these devices.

nHancer allows you to create different profiles to get the most out of each application. It supports Windows Vista and DirectX 10, and also with SLI technology.

If you don't know exactly what to do or modify, don't worry, nHancer includes a detailed description of each parameter that can be modified.

It can be run when aTuner or RivaTuner is being run ad it will detect the changes made by the other programs.
