Black Screen when you want Rust in fullscreen.

Hi guys. When i wanted the game in fullscreen - i’ve had just a blackscrenn and i couldnt even Ctrl+Alt+delete so i should restart my PC. But i found solution. Here it is! It’s in Russian, but ask me if you didn’t understand something. You must have Fraps to be on (but on some computers you don’t) http://youtu.be/ynrRNFCEBww

What?
