The game is still pretty shabby for me in Multiplayer at least. I can play in SP at Med/High settings with no issues at all, but when I try to join a MP server with any settings above lowest, the game freezes on the first frame just after creating a plane.
If I join on lowest settings it will run fine for about 15 mins, but will suddenly turn into a slide-show and lock up a few minutes later. So unbelievably broken for me
Have tried everything I have seen so far, new vid drivers, delete the cache, aero off, reinstall. Nothing helps

My PC isn't exactly a monster, but it runs fine in SP with loads of AI, but MP just murders it
