[Wine] State of Steam Games

[fsleeman]

What is the current status of Steam games in Wine? Some people claim same or better performance than Windows and other say its much worse. At least with TF2, the game goes from great performance with decent settings in Windows, to barely playable with all settings on low in Wine. Can Steam games run well in Wine without having a machine so powerful it can overcome any software problems? Is there a list of games that run well (i.e. frame rate) rather than just "correctly" like on the AppDB?
