DX10 Gaming Performance Review - Catalyst 7.10
Single GPU Performance

The move from the 7.9 driver to the 7.10 "Shoot-em-up" Catalyst update didn't have much of an effect on our single graphics card performance at all. In only one or two instances did we see any changes, and neither was what I would call "drastic" enough to change my opinion on the HD 2900 XT for the current generation of DX10 games. The HD 2900 XT is a solid competitor against NVIDIA's 8800 GTS 640MB, but the Catalyst 7.10 driver hasn't done anything to overtake it.

Multi-GPU Scaling Performance

The real magic of AMD's Catalyst 7.10 update comes when you plug in a second HD 2900 XT card -- our CrossFire experiences with this driver were WORLDS above what we had to deal with on the 7.9 driver revision. In all of our games we saw notable improvements in the scaling of CrossFire and in some cases turned a negative performance gain into a strong positive one. In Bioshock we saw a 54% gain in CrossFire performance, in Company of Heroes we saw a 73% gain and in World of Conflict a 93% gain. The other two titles, Call of Juarez and Lost Planet, which already had CrossFire scaling with the 7.9 driver, still saw improvements of 9% and 20% respectively when tested with the new Catalyst 7.10 drivers.
