Just rename the supplied .exe file to .zip and decompress it into a new dir. After, replace the attached file with the one into this dir. Reinstall driver, but i recommed you to uninstall previous drivers first, because it is possible you can't get a correct refresh rate.
your modified inf file made the v sync option in direct 3d settings gone, any way to get it back?, everytime i reinstall, any nvidia drivers now it still isnt there.....and it didnt fix the refreshrate either. ive been at it all night and day, im out of options lol.
