Mobility Radeon 9600 with 64MB VRAM.
I'm not too fond of using Catalysts again, as I said, I've grown to love custom resolutions and other tweaks that I have no time to manually implement, nor the knowledge of how to do it, of course :P
+ I'm kind of obsessed with latest-versions, downgrading Omega's seems to be a bit hard for me too
I'm thinking I'll wait till the new Omega's, see what they'll do, otherwise I'll send an e-mail to the author.
