1070 and 1080 gtx should run on everything maxed out and msaa x4-x8 Inc Max Distance View Vegetation at 1080p or 1440p.
with gtx 1060 3gb maxed details but distance view , msaa vegetation and 1080 should run above 30 fps stable.
with gtx 1060 6gb you should be able to msaa and increase distance view and 1080p.
And with Radeon graphic cards prepare to sell them cuz they all suck no matter what u tell to anyone they will suck They were made for RAW POWER.
I bet this final release won't fix problem for old graphic card users but It will fix Stuttering Spikes and such but not stable framerate.
