Re: FPS stuck at 60fps after the recent update
I had this, but not after an apex update. Instead, mine was after a graphics driver update. I tried different launch settings like -fps_max unlimited in steam and all that. I messed with it for like 30 minutes and found that when I set the display mode to "Borderless window," it broke past the 60fps cap; I had it on fullscreen before. Now at about 200fps in menu and 130-160fps in game.
You could try reinstalling the game as well if you still can't get it to work.
