For me, the ATI Catalyst 11.10 Preview 3 made my game run fine, so I guess you should try it out too.

Just throwing it out there.

game crashes, ten minutes later from started, every attempt to save game also results on crash, sometimes textures still with the problem, but it fix my problem with high res textures, with the previous driver they look with the blue blocks issue

i've got
phenom x4 925
hd5770 msi
4gb ram
msi 880gm-e41

I crash every 10-15 seconds with preview 3. In preview 2 I was able to play indefinitely, but with hundreds of tiny black boxes everywhere. Still broken here.
Still turning away sales at my place of employment. 36 copies denied and counting, and off to work another day. I average 3 or 4 folks a day I talk out of purchasing Rage or preordering Skyrim, and I will continue to do so until my game is fixed.
Still out 60 bucks
