Well, actually there is a small problem on my system. In game main menu and movies there are black glimpses on the screen. In rc4 I've found solution to fix it. I've set AA in game configuration utility and glimpses were gone. I couldn't make it in the game itself - option was forced off, but if you don't change game options ingame, AA was working and there were no glimpses. I couldn't make it on in configuration file too - game on start erased changes in it. But set in configuration utility it worked. In rc6 I've had a similar problem, so I've tried to fix it the usual way. But configuration utility under rc6 is not working - it gave me an error, saying that I haven't got proper DirectX version installed. I've tried to force AA in Nvidia Display Settings, but in this case I've got a black screen after starting a new game - only menus were visible, but no 3d graphics. However this problem isn't big - it's just glimpses in movies and no in-game AA after all. But still it's not very good - in rc4 everything worked almost fine. I don't know if problems have something to do with hardware. However my configuration is Intel Core2 6320, 2Gb of RAM, Geforce 280GTX with proprietary driver installed.
