It seems to have problems but I think they already started with 7. Most common one is a crash thanks to the intro videos but that's fixable. http://www.youtube.com/watch?v=AHcRsuiKo08
It works fine for me usually but the widescreen fixer mod thing makes the game crash during start up like 90% of the time. Sometimes it works, couldn't get it working reliably at modern resolutions though.
