well, what other programs do you use regularly ? catia, solidworks, pro engineer ? since the autodetect feature of the firegl driver uses a default profile for opengl caps in the specviewperf and maya uses a different setting ( at least in the original atiogl.xml) this performance gap showed up in the first place. the specviewperf10 might not be very reliable concerning the performance in other programs, and those performance gaps between real world applications and the specview results might also show up with other programs. if you use another program that is benched in specviewperf also, it would be great to see a comparision between modded and unmodded drivers. this could reveal the lack of performance in other real world applications. if thats the case we could see if there is a solution to speed up those other programs also by editing the workstation profiles.
