I have XP and Vista installed on separate identical hard drives in a dual
I keep all drivers
up to date for both systems.
The same programs are installed in XP and Vista.
Obviously they are running the same Nvidia card, the Vista side having the
"benefit" of DX10.
Unfortunately, even with the beta SP1 for Vista installed Vista remains time
by your wris****ch slower in every operation including file installation,
file move/copy, open and close any program. Vista hiccoughs frequently on
internet streaming media.
Your results suggest that in your case a pig can fly: maybe yours can but
nobody else's can.
