Didn't get much time to play with it last night, and only skimmed through the SimHQ thread, but I didn't see anyone mention fiddling with affinity of CPU cores for the COD.exe, going to try that tonight.
As has been mentioned, it's not as polished as it should be, but that'll be resolved I'm sure.
Of course Aces is still my go to game of choice, but it's nice to have alternatives.
