--- Comment #5 from Matthew Thompson matt.t.911@gmail.com 2010-03-23 02:14:41 --- I confirm that this is an issue in Wine. Major lag with games tab open, causes problems with running games as well.
Workaround: If you close the Steam interface as your game starts, the issue doesn't affect the game. Tested with CS:Source.
