Issues with Gameplay

Hi, you can force your system to use your primary GPU by going to settings-system-display-graphics, click the add desktop app button (if it's not already in the list) then click the game dropdown and select high performance followed by your primary GPU.

It has already used my primary gpu

ok, what settings do you use in the  game? and what are your pc specs?

I am using the lowest settings, bordered or fullscreen 1920x1080 vsync off
