This small PR is aimed to provide smoother experience for high refresh monitors in main menu when player is not connected.
Current limit is below 88 and not stable because of how frame rate limiting is designed.
I had to change Sleep function call behavior to make frame limit work properly in main menu.
Sleep(1)freezes thread for at least 15ms (instead of 1) on average because of default timer resolution in Windows (64 times per second). And since thread isn't busy in main menu it prevented setting high refresh rate. So I changed Sleep call spare time from 2ms to 10ms (in my case 4ms was enough during testing but I decided to go with 10ms).This also fixes bug with unlimited FPS if deathmatch mod is loaded when not connected (i.e. opening "host game" window).
