Hmmm...
The settings of my drivers? I don't have any settings. I mean I do have settings, but I didn't change any of them, I just installed the drivers and started playing games.
I'm using detonator 7.58 on my TNT2 ultra(which may very well be more powerful than your card). I have never seen a TNT2 m64 in action though so I don't know how it compares to a Ultra. I know the Ultra is more expensive though. Also I overclocked mine(as you can see in the second post of the thread).
You can get all the detonators at
3Dchipset.com
I got mine from some other site that doesn't exist any more.
Do you know how to install the drivers so that you can choose which type of TNT2 you have?
Look at that 2nd post for my Pete's OpenGL 1.51 settings.
