Cool - I'm going to check it out and see if there's any difference to the preview of it. Will report back in a little while..
Edit: Disappointing results. Seemed to freeze a lot - like once every 10 seconds.. I do not recommend using this driver (unless it's working fine for everyone else. Maybe, who knows?)
Spoiler I'm seriously wondering what the AMD driver creators are smoking - this is like the 7th broken driver or somewhere around those parts..
Previous driver I used was fine though (It was either the 12.1 Preview or 12.1a Preview driver)
System Specs:OS: Win7 64-bit Home Preium
Misc: OS+Steam+Game on same HDD (lots of IO bloat, but w/e)
GPU: ATi Radeon HD 5850
CPU: AMD Phenom 965
RAM: 8 GB DDR3 1333 MHz
Lo Guys.
I experienced some long freezes (more than 1 second) during the first half hour after installing this driver (level: Prison), but since that, I played more that five hours without any prob. Perhaps the texture cache take time to be re-created with new parameters, don't know.
I think like u that getting system + cache + game folder on the same hard drive can't help!
Try to load various maps during some time, minuts, and get out of the game, to reload it, perhaps it helps (i hope!).
About the update, i found http://www.idsoftware.com/, there is an iphone update available, ours (PC) is near, i just hope it wil be free for us, regarding what happends for PC gamers

.
Anyway, good news

, no?
Seeya.
