Have you seen the blue screen yet? Since I rolled back I haven't seen it, but I don't know if it is due to the roll back or because so many registry errors were fixed. Or both. or it just plain hasn't cropped up yet. And I hope it is not the latter.
I haven't seen a blue screen in quite a long time, with any version of ATI drivers. I think it was 2 months ago when I saw a single BSOD during testing of one of the 12.11 betas.
I tried this uninstaller last night as I had run across something called a "modded FirePro driver" that was touted to work on the Radeon HD cards. I tried that and found it was functionally identical (including problems) to the Catalyst 12.10 drivers, which misreport the amount of graphics VRAM to Photoshop.
There just aren't good drivers yet from ATI. I think they know it; we're not the only ones talking about it.
