I don't know why the game is capped at 142fps instead of 144 and because of that I can't use my LG's ultra responsive mode but when I play full-screen I am capped at 138FPS but in full screen borderless I am capped at 142fps.

None of the other games that I have played which support 144fps have this issue.

In-game configuration
Resolution: 4k (Doesn't matter, it caps it no matter how low I go)
Graphical settings: Max everything (Even on lowest it is capped the same way)
