I also have 144hz screens, and with vsync enabled the fps tends to cap at either 60 or 72fps, reaching 120 only with barely anything on the screen. (But that's what I get for running a system with a cpu from 2011)
Disabling shadows, godrays and framebuffer thrusters tend to be easy ways to gain a lot of extra fps.
Gigabyte GTX 1060 6GB VRAM
16 Gb of RAM
Any way to possibly alleviate my FPS issues?
