Dual-Core config edits.

[Ultron]

The game automatically recognizes multiple cores and scales threads to them. No console command needed.

Go to this thread to read about how the Dual Core Optimizer helped there. Might be something of worth to you.

Hi, I am getting unusually low FPS in UT3. It was the same for Team Fortress 2. That was until I opened the console in TF2 and typed in "mat_queue_mode 2" which has something to do with dual core systems. Then I got double the FPS. Is there anything similar for UT3?
