I know that im going to catch flak for not expecting this, but this is a bit overkill. i was running 3GB's, sometimes 4GBs of RAM usage in 1.5.8OA, Now im running over 6.1 Gbs and 2.3GBs page-file during loadd, and 5GBs once in and loaded, this makes multiplayer impossible. framerate wise everything is fine* for the most part.
*minor expected drop of about 10 frames.
Specs(I used to get 160FPS on high settings in 1.5.8OA):
Pentium G4560-3.5Ghz-Kabylake
EVGA 1050Ti 4GB
8GB RAM
I was expecting minor dips, and actually getting in game is fine on single player, everything looks stunning, but the load times are absolutely horrible now.
