fps affects frame-rates
Digital Foundry conducted a test, which showed that players who have 30 or less FPS lose in firing speed. In other words, the lower your fps, the less damage your rapid-fire weapon does. The difference in the rate of fire between 30 fps and 60 fps is 5.2%. At the same time, the difference between 300fps and 60 fps is insignificant.
Lots of discussion about higher Fortnite fire rates with higher frame-rates. We noted a 5.2% increase in fire rate at 60fps vs 30fps in this test, but no further advantage beyond that. Epic says it will be fixed in an update. pic.twitter.com/lmbgNOhrLR

It seems that the difference is insignificant, but when a whole store is depleted, a player who has a low FPS loses much damage. Another problem is cross-play. Mobile phone players and the Nintendo Switch were initially in a losing situation during a shootout with any other console.
Epic Games has already confirmed what they know about the problem and are working on solving it.
