Similar problem here.
With Snow Leopard playing WOW always got me about 50-70fps.
Now with Lion it dramatically dropped to 20-30 fps and unbelievable slow mouse response.
Everything was newly installed.

Check to see if ATI came out with updated drivers for your graphics cards. NVIDIA cards were having similar issues with both League of Legends and Steam games. I saw on a forum for League of Legends that NVIDIA had come out with an updated driver specifically for Lion OS users. I did try checking on AMD's website to see if they could be found there so I could give you a link, but I couldn't find anything. So, perhaps there might be a way to manually check for an update for that driver specifically or email someone at AMD about it?

Got the same problem. System works great on fresh boot. After sleep serious drop in performance. OS animations choppy, full screen video (quicktime or flash) unwatchable. Can reproduce this problem. Presently the only fix I have is disabling sleep in power managment.

Same problem here. iMac 8.1 (C2D 2,8GHz, 6 GB RAM, ATI Radeon HD 2600pro).
As Kersten Lohmeyer wrote, especially fullscreen apps animations and opening Launchpad folders are extremely choppy.
On MBP 15" 5.1 (C2D 2,53 GHz + 8 GB RAM) everything is flying.
I can't believe that this graphics is too slow for Lion.

Similar configuration to above posters, and everything snappier in Lion...except playing WoW! Atrocious fps (ie 3-5 fps) unless reboot with nothing else opened, then start WoW and get about 18-20 fps. Still horrible and hope Apple fixes soon.

I am having the same problem with my 24" iMac Early 2008 ATI Radeon 2600 Por 256MB vram, its pretty abd when the Intel GMA 64MB on my Mac Mini running lions runs more smoothly than the ATI HD card, seriously rollercoster tycoon 3 is freezing like no tommorow on the iMac, runs smooth on an Old 2006 Mac Mini with Intel 64MB GMA card. There both fresh installs of lion and rollercoster tycoon 3, APPLE please fix. Minimizing and maximizing also freezes on the imac but not the mini.
Also restarting the computer, and turning off sleep is a temp fix to the problem.

Same here!!! On fresh reboot my iMac (24-inch early 2008) is fast and without problems, but after a while there are the same issues. I hope Apple will fix it soon...

YES. Early 2008 imac, video performance after lion upgrade is not watchable.
