Like others, and about a million posts before me, I cannot get my TNT2 Ultra to go above 60hz when playing opengl games. I know all about the dxdiags (but it does not support opengl) and I have modified my .inf file for the Nvidia drivers but it does not seem to work. After modifying the file and trying to play Quake, the game crashes out as if it does not see the 60hz and does not know what to do. I re-installed the driver without a modified .inf file and quake and other games work fine...but at 60hz.
 
I do believe I modified the .inf file correctly (leaving the 0's and spaces in the correct places)
 
Any and all help is appreciated.
 
Thanks,
 
Troy
