PPSSPP offers graphical features that are enhancements over the PSP's capabilities, such as higher screen resolutions, antialiasing, image scaling, support for shaders, and linear and anisotropic filtering.

[6] Since its inception, PPSSPP has had a focus on portability with support for multiple architectures and operating systems.

While initially only supporting Microsoft Windows and Android, this quickly grew to include Blackberry 10, Symbian, macOS, Linux and later iOS.

To aid with the portability, two cross-platform development libraries—SDL and Qt—are able to be used in addition to the non-portable Blackberry, Android, and Win32 interfaces.

The App Store release lacks the ability to use just-in-time compilation due to restrictions by Apple, though the developers also noted that contemporary Apple devices should be able to run most games at full speed even on an interpreter.
