Lion graphics extremely slow with Radeon HD 2600 Pro 256MB

Made a clean install with Lion and it now turns out that the graphics (Radeon HD 2600 Pro 256MB) on my Core 2 Duo iMac are way to slow (or insufficient VRAM) for the Lion UI.

Especially fullscreen apps animations and opening Launchpad folders are extremely choppy. Not much fun the way it is.

I mean come on, a mac, which can play WoW pretty well should be able to push 2D Graphics around, right?

When booting up the UI is fast, but after letting the iMac on for a while or waking it from sleep the graphics are choppy again.

Anyone else having this problem?

Regards,

Kersten

iMac, Mac OS X (10.7)

The release notes for 10.7.3 state "Address a graphics performance issue after sleep on some earlier iMacs that use ATI graphics." Can anyone confirm?

10.7.3 has finally fixed my issues on my iMac.... better late than never. 🙂

10.7.3 did NOT fix the issue on my Mac Pro (early 2008) with Radeon 5770.

Can anyone tell me, what version of ATI* extension files you have? I have 7.18.11. I'm trying to understand, why update didn't help me.

Yes! The 10.7.3 update finally fixed all graphics related problems with my iMac 2.8GHz (early 2008) ATI Radeon HD 2600 Pro.

Thank you Apple!

Latest update didn't solve the slowdown on my Macbook Pro 17" early 2006 (A1212). User interface is still incredibly slow, much more painful than on 10.6.8 on the same tasks.

I have same driver version and 10.7.3 don't fix my problem.... at boot the performance is good, after wake-up safari scroll the pages in some sites very slow!!! I have radeon6870, i suspect the fix is only for older gpu...

At the moment the sleep is unusable.
