Win 10 64-bit
144hz GSYNC monitor (ACER XB270H)
The game runs very clunky when I run at max or at minimum using my native resolution 1920x1080… When I switch to 1600x900, the game gets slightly blocky as it should at a lower resolution BUT the game becomes very fluent @ 70FPS most of the time at max settings. Then when I switch back, its back to clunky/sluggish gameplay.
Feels like a bug or just some strange optimization issues.
