Go to Nvidia Control panel and set Power management mode to use prefer maximum performance and change maximum pre rendered frames to 3.
Boom. Stuttering gone
IF THE ABOVE DOES NOT WORK, TRY THIS IN ADDITION TO IT:
Open the GamerProfile.xml file with Notepad Find GPUMaxBufferedFrames=”0″ and change to GPUMaxBufferedFrames=”1″
and also DisableLoadingMip0 =”1″. You don’t have to do this to eliminate the stuttering but it wont eliminate completely, there will be slight micro stutter to the well trained eye. try it.
