4890 - slow in l4d2?
XFX radeon, OC'd to 975/1150.
__________________I've taken the settings down to 1280x1024 and turned off all of the AA - filtering mode = bilinear, vertical sync = disabled. This'll net me about 200 fps standing still. If I turn all of those up I get about 40 fps...this really doesn't seem right? My buddy has all things maxed and is at 1900x1080 on a 4870 1gb and is getting a ton more fps then I. Btw - this seems to be the only game i'm having this problem with. If it is a problem. Any ideas? I really didn't know if I should post this here, or in the pc games thread (this seemed more appropriate). Thanks much.

How did you install the latest one? Did you completely remove the previous one, booted up safe mode and cleaned everything with Driver Sweeper? If yes, then the 9.11 has a problem with that game. Go back to 9.10.

I definitely did it the slacker way, just installed over it. That's a no-no I imagine?

No because in 5/10 cases you have performance problems. Please uninstall everything, reboot in safemode, use this tool : http://www.guru3d.com/category/driversweeper/ Then install 9.11 again. If the problem persists, redo the procedure and install 9.10.

1) Lower the OC on the GPU
2) Check cooling, set fan throttle to constant 100% via rivatuner

Yea I have a 4830 in my sig-rig at the moment, getting constant 60fps at 1680x1050 everything maxed. A 4890 should be destroying the game on the OP's setup, and the 4850 you have should be plenty as well.
I should note during explosions (like from a grenade launcher), the smoke causes my FPS to drop to 30, but that is the only time it drops.
