[Gameplay] FPS drops since patch hit, linked to locking fps at 60

I've been having some frame rate issues since the latest patch and found it went away when I uncapped my FPS instead of capping it at 60.

With it capped the game stutters and showing 59 fps at times, but dropping way below.

With it uncapped the game dances between 140 and 80 FPS but doesn't dip below 60 as it did when I was capped.
