 - Added 3840x1600 and 4096x2160 video modes.
 
-- Added 160Hz and 240Hz refresh rates. 
+- Added 160Hz and 240Hz refresh rates.

+- Added automatic setting of r_maxfps based on refresh rate set in video menu (r_displayrefresh).
 
 - Added support for triple-monitor surround modes via custom resolutions.  Monitors must be bound as a single logical display.
 	Keeps all menu/HUD elements on the center screen, set the cvar scr_surroundlayout to 0 to disable this.
