heavy stutter

[fiendish78]

in dx11 game is still stuttering like hell when i move/zoom the camera. its strange, because in dx9 game runs perfect on max settings. could it be realted to the motion blur effect? is there a way to remove it? they said the latest update should had solved the problem but i got no change at all. i have a radeon 6990 with cat 12.2

How do you get it to run in DX11?

Edit: Got it. You have to run in compatibility mode for Windows 7. Go figure!

now, how come that, with the same level of detail the game lags brutally in dx11 while literally flies in dx9? is crossfire broken in dx11? am i the only one experiencing this racket?

What quality is ground set to? i find if it is above high in DX11 my game stutter like hell, i can have it set to insane in DX9 but really i don't mind playing with it set to high.

in fact, i solved the problem by disabling crossfire. for some reason, my radeon pro software is unable to modify the settings for this game, so i had to do it by the amd control panel (cat 12.2 has the option to control which crossfire mode to employ). game now runs smoothly in every situation i tried while maxed out. i must say i'm disappointed by the lack of care crossfire users are receiving; lately, too many games run better with only a single gpu enabled. If you have a double gpu radeon card you should try this, if there are several of us with the same issue we could request amd and/or the developer to release some updated profiles
