Most---->Least Important(my opinion)
-Multi GPU fix (should have been day 1 hotfix)
-Cutomizable GFX settings(we've been whining for this since the demo. Should have been day 1 patch)
-^ along with GFX glitch fixes(same ones present from the demo XD)
-Multiplayer issues in general(Let this be done by the time I finish singleplayer...almost there)
-DX11(yeah, I can wait... Should have been done before the release of demo)
All and all, PC version of this game is incomplete. Gameplay, sure, it's the same as the consoles. But user friendly interface and reliability is total BS.
P.S: And how the hell can I access the console in game??(Steam)
