Fortnite: How to Fix FPS Drops (Stuttering + Low FPS)
To fix FPS drops in Fortnite on PC, do these fast fixes. Update your GPU driver, then restart your PC. In Fortnite Video settings, lower shadows, effects, and post processing, turn off motion blur, and cap FPS to a stable number your PC can hold. Use Performance Mode if you want the best FPS.
Close background apps like browser, overlays, and screen recorders. In Epic Launcher, verify Fortnite files. Make sure Fortnite is using your high performance GPU in Windows Graphics settings. Also set Power Mode to Best performance on laptops and keep the charger plugged in.
If stutters started after a new update, clear shader cache and let the game rebuild it by playing a few matches.
