Are those the 177 drivers?
I'm waiting for those as well. They should fix some issues with XP + 8800GTS 512. Something with how XP handles shaders. Doom 3 (among others) is completely unplayable as it stands now. Oh well, quess I have to hold out till a XP x86 version. Glad to hear they actually fix some issues,
like Nvidia promised (heard that before

).
*in response to below; Awesome, you're the best, would love to try them out.
