(In reply to comment #4) As you can see the usage for the first core is 100% and for the second is 20-30% so it seems like the second core doesn't work.
20-30% is some load, rather than none which looks reasonable, but have you verified that the 100% isn't just the game on one core and then maybe Xorg on another, or wineserver, or some other process?
The picture doesn't illustrate which processes are using which percentage of cpu.
