Why is Fortnite broken on PC? (Stuttering or frame drops right after a content update)
Smooth gameplay before a patch, then stutter or FPS drops in the same matches afterward. New shaders compile on first load after an update; this is a one-time cost but feels like a permanent performance drop if you don't wait it out. Fix: Let the game sit on the lobby screen for 1–2 minutes after a major update before dropping into a match — this lets shader compilation finish.
