First D/L Driver Cleaner Pro. (MajorGeeks.com or guru3d.com)
Run that to clean out Nvidia VIDEO Drivers. Do no select all Nvidia drivers as you will loose your motherboard drivers as well. (If using an Nvidia Chipset board).

As for video drivers, I'm using the latest drivers and getting 204fps with Vsync off. 64fps with it on.
I usually leave it on due to the use of the Track IR. You get vertical tearing if you turn your head fast with Vsync Off.

thank you for the response! whithout the drivers, will the graphics card work?

EDIT: the Driver Cleaner Pro has a price tag to it?

EDIT #2: THANK YOU!!!!
