I just tested Simcity 2013 offline mode and the FPS is so low as to make the game unplayable. Of course I play via POL so it could be part wine's fault. Then again this is EA we aree talking about so mabey they do have some bugs. The only thing in the POL log that is realevant to Linux is 'ALSA lib pcm.c:7843:(snd_pcm_recover) underrun occurred' but that might not be POL's fault. It might be part of the FPS problem. I tried turning down the graphics in the game but it didn't seem to do any good.
