ovo sam našao kao postupak, ne znam ako radi

Before doing this, my 64-Bit exe would hang before the main menu.
1). Launch the game using the 32-bit executable first
2). Settings/Advanced - Set Post Processing to High (HUGE FPS Gain no matter the resolution - I game with crysis @ 1680x1050 16:10 22" WS )
3). Now choose your normal resolution
4). Launch a new game atleast once, then exit
5). Now open 64-Bit executable and you can do 64-Bit

Now it works!

This one didn't work for me, but others have had success
If that doesn't work for you, then try this:
1). Launch the 32-Bit application first
2). Goto options "uncheck fullscreen" and save then exit
3). Launch the 64-Bit version

ALWAYS CREATE A SHORTCUT TO YOUR DESKTOP!!!!
RIGHT CLICK AND CHOOSE "RUN AS ADMINISTRATOR"

Just thought I would post some workarounds for those having trouble getting the game to run.
