I tried using the Omega drivers this weekend and it made my system very unhappy. I don't think they work with the new GTX 260 core 216's at all. So I went back and ran the drivercleaner pro utility and installed all the latest drivers again and had no luck. Even on a single instance running in Dalaran I cannot crack 20fps. If I reboot into xp its 60+fps no problem. I think tonight I am going to blow away my XP 32 install and install XP 64 into that partition and give it a whirl. I"m aware there is an issue where you get half fps across two monitor using XP but I think even with that I would be better off. If anybody has feedback or experience with xp 64 I would love to hear from them.
