As it stand I today have the impression that ATI focus on FireGL performance and that they currently don't want to improve the drivers too fast for Radeon so it is almost on par with the FireGL. The difference appears almost too large to be credible as it stands. Previous FireGL/Radeon card may have had similar results (

So, I guess if the same or similar FireGL/Radeon difference is retained in Windows then it is the card difference we are seeing and not only poor drivers for the Radeon series.
