Ive clocked over 2 days playing time (now being rank 36 after 1st reboot) and i must say the DX11 should absolutely not be the priority here!
multiplayer needs fixing before Crytek gets busy with graphical adjustment...
lack of DX11 is not as gamebreaking as LAGGY SERVERS WHEN ORBITAL/GUNSHIP is out or AIMBOTTERS running around ruining the fun... not forgetting unlocks that lock after logging out again and rubber-banding ranking system
Rubber-banding what? Please explain.
The rest of your post is inane because they are not universal problems at all. I never see any lag from any killstreak. Leaving servers and going into ones with admins gets rid of aimbotters, and the unlocks is simple. Just leave from a game lobby to update your profile.
