I didn't spend much time on it though considering my copy is arriving tomorrow via UPS. I tested with the campaign unlocker (and skirmishes). I'm surprised nobody else reported the issue with the Source Engine, since those games a largely played. I dont have any hl2.exe based game installed on this computer actually, I might give tf2 and l4d a try (I can run Urbanterror, Dawn of War and Stronghold Crusader just fine, so we can assume its a source engine related issue).
