i have two 7950s in crossfire, and i am going to be getting fallout 3, and new vegas. But i heard that dx9 games (these two in particular) dont play well in crossfire? And im not sure but hasnt frame pacing only been added for dx10 and dx11 games? Would it be better just do disable crossfire when i play them and just use one 7950?
 
Solution
either way fallout nv will run on ultra no worries with just a single 7950. so if you see stutter, just disable crossfire. ,microstutter is not resolved in dx9 titles this is true, but another way to remove microstutter completely is to enable vsync, and keep your fps high enough to be hitting vsync most of the time, which they would certainly do in that game, either that or a frame rate limiter if you dont like vsync.
