# PPSSPP iOS Running Slow / Lag Fix — iPhone Performance Settings

I installed PPSSPP on my iPhone from the App Store but some PSP games run at half speed, stutter, or drop frames constantly. Games that should run smoothly — like God of War: Chains of Olympus or Crisis Core — feel slow and jerky. My iPhone handles other games fine. I haven't changed any PPSSPP settings from their defaults.
