I wanted to play some Doom 3 on Steam after finding a possible method to get surround sound working but I'm getting terrible performance.
I'm running a Core i5 2500K @ 4GHz, 4GB RAM and an Nvidia 560Ti running the latest beta drivers (304.79).
I've tried verifying my game files and disabling the Steam overlay but neither has helped. I've also tried Prey and Quake 4 which use the same engine yet there's no issues with those games.
EDIT: Fixed by rolling back my Nvidia drivers to 304.48. Something in the 304.79 drivers is killing performance.
