everytime I play fortnite out of no where it feels like i'm playing on 60 to 30 fps but my fps is stable 76. It happens for a few seconds then goes back to normal. I have a acer 75 hz monitor 1ms vrb gaming. I have also noticed a little problem whenever I'm running a recording software in the background it feels smooth but when I'm not it feels choppy my whole game is choppy.
