Which "ingame" games only require more performance before they can be "playable"?

Anyone who knows a game that has graphics that are good (small issues are fine) working sound and are only stuck in the "Ingame" category because of slow performance?

I want to compile a list of games that meet this criteria so when optimizations come we know which games to retest and potentially move to playable.

Feel free to mention games that were tested on low-end hardware and may otherwise be playable on a decent PC.
