Hi Oyveye,
I went from the Creative Labs drivers for me Geforce 2, to the Detonator Three Drivers (which BTW, is the same thing as version 6.31 which I don't understand, but that's what Device Driver tells me!) and saw a big boost in performance. My 3DMark scores did go up, but not by too much. The main diff I saw was that games were a lot "smoother" for lack of a better term. 3D objects had more visual clarity...that kind of thing. It's worth upgrading to them.
BTW, after upgrading the driver, I did have to go and reset my monitor resolution and refresh rate, but it wasn't a big deal. Everything works fine.
On a parallel note, I'm now trying to decide whether or not to upgrade to the latest "unoffical NVidia driver" the 7.51. Go ahead and use the Detonator Three, it's good to go.
