Can anyone that has an ATI Radeon and UV Mapper tell me what the start-up screen says as far as OpenGL drivers. Does it say ATI Drivers or Generic Microsoft drivers (Software OpenGL). I have a system with 2 cards and share the moniters, but dont get ATI OpenGL. ATI told me if I had one like the ones you're mentioning with a VGA and DVI all in one card it would work on the Primary. I'd like proof! It can work fine with one display, but with 2 allot of times Windows loads the software drivers instead of your cards. I dont know of any other way to truelly check without UV Mapper's start screen. Thanks if anyone could check.
