Ive heard of the AA issue. Ive also heard that the Tribes2 engine was primarily designed for nvidia cards, so thats why there is no problems with them, but Radeons have loads, like the AA issue, poor performance, ect;
I have a 9700pro, so yes, im on about the r3xx series.
Ive had Tribes2 for a bit, but never played it much before, cos when i got it, i had a 56k modem, so i was stuck with SP. But now i have ADSL 512/256, and i wanted a team baced game to use online, i was going to buy BF1942, but then realised i had Tribes2.
