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.

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.
