I've not updated any dirvers at all, just use the standard bootcamp ones in XP.
I play crysis at 1920x1200 (all my games run at that resolution) around 25-30fps with all settings maxed bar one (shader something I think). Tried it on ultra high but it was too slow and I wanted to avoid lowering resolution.
BF2 and BF2142 all maxed out including increasing AA and AF in nvidia control panel to 8xAA and 16xAF (beyond in-game settings). (8xAF for 2142, not bothered to try 16x, but it is more demanding). Not checked fps, but must be 40-50+
Supreme Commander maxed out everything, around 30 fps on performance test, though real gaming is far more demanding as I play very long games with many sides, though I play without AA as find it makes little visual improvements for that game, yet when you get to having 7 sides with an excess of 750 units each it makes a performance difference.
(as a side note, my iMac plays supreme commander smoother than my friends quad core 2.6Ghz 4Gb Ram 8800GTS SATA raid PC, and he runs at "only" 1280x1024, though he does max out AF and AA pointlessly)
Source games are all fine, though oddly portal seems slightly jerky with motion blur on, though TF2 doesn't.
Oh, and GTA2 runs crazy fast with the frame limiter off!!!
These frame rates are no doubt completely unacceptable to many (i.e. 25-30 for crysis), however I'm very much a person who likes pretty above smooth, and am used to frame rates more around 15, so its great for me.
I'm very impressed with it to be honest, just not sure if I should get updated drivers from nvidia or not.
Have people found that drivers from nvidia give better performance over the bootcamp ones? If so, are there any other drivers I should update? (XP, not vista).
