ATi Catalyst 9.1 Performance Review
OpenGL
Sadly Prey’s performance doesn’t change at all on my single 4850; perhaps the gains are only visible with Crossfire configurations.
Performance elsewhere largely stays the same, except Quake Wars which sees a large 17.44% performance gain. This victory is again questionable on a 4850 due to the low scores in both cases, but it could be important to a 4870.
Really appreciate the driver comparisons you do. It makes me wonder where the vendors get their evidence concerning the % increases they claim under various titles.
Hey man, glad to see you join us.
The vendors probably get their figures from very specific scenarios (e.g. 1680×1050 with 4xAA), but it’s sometimes still possible to see lesser performance gains in other situations.
