To get the best performance out of a Call of Duty Modern Warfare 3 ISO on PPSSPP, certain settings are essential. Because these mods often use higher-resolution textures than the base game, you should enable "Buffered Rendering" to prevent flickering. Setting the rendering resolution to 2x or 3x PSP will make the modern weapon models look crisp on a smartphone or PC screen. If you experience lag, enabling "Skip Buffer Effects" or "Lazy Texture Caching" can provide a significant frame rate boost.
These mods are usually built upon the engine of Call of Duty: Roads to Victory, which was the only official Call of Duty title released for the PSP. Talented modders take the framework of Roads to Victory and inject custom textures, weapon models, and sound effects from Modern Warfare 3. When you load one of these ISO files into your PPSSPP emulator, you are greeted with a UI that mimics the MW3 menus, featuring the iconic green-and-black aesthetic and familiar background music.
