To fix PS5 performance issues easily, start by restarting your console to clear temporary glitches. Make sure your system software and all games are fully updated. Clear out unused games or apps to free up storage space, as low storage can affect performance. Rebuild your PS5’s database by booting into Safe Mode and selecting “Rebuild Database”—this can fix lag or crashes. Also, check for overheating; make sure the console is well-ventilated and dust-free. If you’re still facing issues, try resetting the PS5 to factory settings as a last resort, but back up your data first.
