I had no FPS issues when I played the last open beta. Hmmm.
Maybe I will download it again...
I don't remember FPS issues previously, but I'm getting < 20 FPS out in the world, regardless of video settings (I get maybe a 5 FPS swing between Ultra Low and Ultra High). I've tried beta drivers, old drivers, forcing DX9 mode, uninstalling, reinstalling, etc. I know my CPU is not the best (Phenom II x4 955), but I mean, it's in the "recommended" settings, so you'd expect that I'd at least be above 40 FPS on at least Medium, when combined with a 7970 and plenty of RAM. From what I've read, it seems that more people with AMD chips/cards are having issues than those with Intel/Nvidia, so I'm cautiously optimistic that it will improve with optimization and driver releases, but it's still kind of a bummer.
