Crysis DevMode help

I've been messing around with the Crysis Sandbox and I can pause physics easily enough (with "," ) 
 
But when I enter the actual game (In Devmode) everything works (F1 - 3rd person, F3 - no clip mode) but when I press "," my physics won't pause. 
 
Anybody ever had this problem? 
 
(BTW thought I put this in PC forum, feel free to move it)
