the new version ppsspp is very slow in ipad4!

Try to activate Buffered Rendering, it should force PPSSPP to render on PSP resolution instead of the absurd resolution of an a iPad 4 (2560x1600 if I remember correctly). You can even activate 2x resolution, shoudn't impact much. But if this is really the problem, probably it will be impossible to have a good performance on iPad 4 on the games that need Unbuffered Rendering to get full speed.
