I just picked it up. It runs okay on low detail at 1024x768. I haven't had time to see if there is a supported widescreen resolution through tweaking, but there isn't in the setup menu. So far I'm not too thrilled with it, but I'll be playing at a lan next month, so I need to get used to it. However, I think I'll bring my desktop to play it.
Kind of wishing I had picked up UT2004 instead.
UPDATE: I just downloaded and installed the latest Omega drivers based on the Cat 4.3. Improved my performance greatly. Still running at the lowest settings, but it's very smooth now, even in the sh**, I mean dense grass and trees.
I also tried the tweak people are using for BF1942 to get it to run at 1280x800, but I'm not sure if it's working. It looks great, but sometimes I get the sense that it's stretched a bit.
It's a fun game once it runs smooth and you have some time to get into it.
