Still no fix for the Q3 engine problem? I'm surprised AMD has allowed the issue to persist this long. I still have to use a 10.4 OGL dll to get Q3 engine games to function. I'll echo Abram on this one...love my 5850 hardware, but steadily losing confidence in driver support.
Drivers always seem to be the thing that pushes me away from whoever I'm currently using. I got sick and tired of nVidia drivers breaking something to fix something else (which used to happen all the time when I was using a 6800GT/7900GTO/8800GT...) then I get sick of ATi drivers never actually fixing the issues I have... vicious cycle there.
I think I'm still running Cat 9.3 on my laptop, as since then all of them just seem to make the 3650 Mobility flaky. Do not want driver crashes in the middle of work. And my desktop ATi based rig is still Cat 9.11 IIRC.
Q3 engine problem? It's been so long since I bothered with a Q3 engine game on anything other than my laptop (Jedi Knight 2 plays great even on "underpowered" mobility hardware. :D)
