How do you edit Nvidia drivers to change refresh rates?

[Pottsey]

I am having no end of problems with refresh rates in some newer games a they keep defaulting down to 60hz. None of the programs are working so my last resort is to edit the drivers. I have been told you can edited the inf file for drivers to make 100hz only mode to show up per resolution. Anyone know how?

Edit: Think I have it but can someone confirm

3B = 111011 => 100Hz=1 85Hz=1 75Hz=1 72Hz=0 70Hz=1 60Hz=1

So what I need is

3B = 100000 => 100Hz=1 85Hz=0 75Hz=0 72Hz=0 70Hz=0 60Hz=0


But what do I change 3B to?

Should have said in the first post I am using Vista 64-bit.
RefreshForce and RefreshLock don’t work. After playing about a bit RivaTuner works but only on some games. The Witcher is being very stubborn and is still at 60hz. RivaTuner did fix American McGee's Alice which is now a nice 100hz.


EDIT: Come to think of it perhaps RefreshLock did work on some games, only tried it on Witcher which doesnt seem to work with anything.

http://www.pagehosting.co.uk/rl/ doesn’t work 100%
Only some games work with it and it won’t auto load with windows, I have to load it manually each time I reboot.

"Yes it does and sure you HAVE to load it each Reboot unless you add to start Menu."
No it does not work 100% it doesnt work with The Witcher. I got it to work with my older games but it failing to work on newer games.

Least its better then nothing. Nearly all my current games work now.
