Doom 3 is limited by the CPU. OpenGL multithreading should help with that. With stock Mesa, there is no way make Doom 3 faster.

When the GPU load is low, it means the app is CPU-bound. Multithreading is the only thing that can help with that.

Hmm, you're right. By default all cores are used 30%, but if I start doom3 with taskset -c 0, it uses 100% of core 0, and I get 35-50fps at 6-8% gpu load. I didn't know tasks were being moved between CPU cores this much. And it seems that my CPU is slower than I thought.
