when the patch hit i would try to load in past the launcher and it just wouldnt! i also noticed it was using way to much ram for a minute or two before telling me it wont launch.
but i fixed it!
i created a shortcut with the -dx11

i was able to launch the game then select the dx11 beta option in the graphics setting, close out and relaunch the game from the normal shortcut. hope this helps someone!
