--- Comment #29 from Lars Blomqvist knaprigt@gmail.com 2010-07-12 17:29:56 --- Has anyone tried to run Steam/game with sound disabled (Alsa and OSS unchecked in winecfg)? At least on my system wineserver seems to behave better with the sound gone.
Note though that I'm running Modern Warfare 2, not TF2, but it seems like the same bug considering wineserver is eating up a lot of resources here too.
