PPSSPP emulator v1.15.3 released for Windows PC, MacOS, Linux and Android devices

All good things come in threes, and the proverb was never more than apt for PPSSPP , the PSP emulator written entirely in C++ which allows us to emulate PSP games by translating CPU instructions directly into machine code optimized to run on chip x86, x64 and ARM.

 

 

The  PPSSPP  emulator is capable of running PSP games on PC in Full HD resolution, and also playing them faithfully on Android, iOS, Blackberry devices and Xbox consoles through UWP.

The program has long had problems with stuttering caused by compiling shaders, and had reached a point where it was stuttering enough to be nearly unplayable on some devices with very slow shader compilers.

These issues have led to a change in compiling shaders that will now compile separately for each little bit of shading state, such as double color value or fog flags.

Also, in Vulkan, shaders are now compiled in parallel across multiple threads, which is a huge improvement on some drivers like those for PowerVR GPUs, a slight improvement on Adreno, and generally neutral on Mali.

The devices that saw the biggest improvements were also the slowest before, so it was definitely worth it.

Among other things, this third update, currently available only for Android devices, aims to fix other minor crashes and a bug in the mapping of the user interface that caused problems with some controllers.
