I have X1800 Crossfire setup and is actually crappy with world of warcraft. I noticed the new Windows XP 6.7 drivers force AFR. Im using Windows X64 and that version of the drivers dont have that feature. Could I use the windows XP drivers with X64 and will they work fine or i can not do that? I really could use that feature in hopes for better FPS. If not is there a way to get the X64 drivers to force the AFR feature??
