WoW and ATI users

[The Mad One]

I wasn't sure which forum to stick this in but since its wow related I thought I'd get a bigger audience here. I've recently upgraded my pc to a X1900XT and using the new cats 6.2 and when I play wow and bring up the start menu or any object like one of those yellow ballons from the task tray the screen lags like anything. This never used to happen on my old 9800XT and 5.4 cats, so I was wondering if anyone else has experienced this and knows of a fix?

As a temperary fix can anyone tell me if the X1900XT will work ok on 5.4 cats as I'm pretty sure this is a driver issue?

I found the problem, it's the multisampling setting in the game setting it to more then x1 seems to trigger the problem described above. I remembered when i first started the game after upgrading my pc i ramped every thing to maximum i found it by turning things off 1 by 1. Can anyone with an ATI card test this for me and see if they get the same? The game will have to be in windowed mode to get the desired result.
