Practically everything. The game is a little choppy at the beginning, but after a while everything runs fine.
This includes the microphone as well, and I could not find anything else that wouldn't work.
What does not
Nothing I noticed so far.
What was not tested
Playing all the campaigns and all the modes. Online play on dedicated servers. Playing on local servers with friends worked however, so I'm going to assume that it works.
I did not change anything in the registry apart from setting video memory to the correct amount. Because of some minor flaws (slight freezes and so on), I'm rating this only Gold.
