ProcessAffinityMask

According to other threads, 15 could stand for all cores. Assumed is that 14 would use all cores except the first (core 0 ). But a table of mask numbers is welcome. I wouldn't use the core in use by Windows.

but the latest patch has optimizations for multicore and its still at 2, i dont get it.

The game doesn't read the config of your system on that matter. Openup the conf.ini to change the affinitymask and change it manually (see post in this forum).
