If you are still having issues with DOOM 3 BFG the new 12.10 drivers are out.

For best results uninstall your old drivers through Programs and Features, reboot, install the new ones, reboot again.

It is very important that you have/get the newest .NET4 from Microsoft for CCC to function properly.

Use the drop down menu on the upper right to select your card type and OS.

This solves the FPS issues others have been having, but NOT the missing effects after helltime bug in RoE.
