Well Fortnite is competitive so you are at a huge disadvantage if you’re only playing on 60 fps, even worse at 30. But at that point just play a different game Fortnite is very poorly optimized
This isn’t really true, I don’t understand how the human eye works, but when running a game at higher than 60 fps it’s noticeably smoother, probably because real life doesn’t actually have “frames” so what is being rendered onto your monitor/tv is much different
