I run Windows XP on occasion on my iMac early 2009 (20"). Lately I have been thinking of trying to update my nVidia drivers as it has been hinted that it could solve some of the problems I've been having.
Right now, I'm running the bootcamp drivers, which work. When I go to nVidia's site to download the drivers and install them I end up with a driver that is unable to go beyond 640x480 at 8-bit color mode.
It could be just me, but somehow the driver shows the card as "nvidia 9400" (notice the lack of the "M") even though the specs list it as the 9M.
Update: Yes, I did try installing the 9M drivers.
Has anyone experienced these issues? Is there a way to upgrade my graphics drivers?
