Guide:- Maximizing the performance of PPSSPP on your Android/Windows device.

I read here that .CSO image is a type of .ISO compressed, and in games that needs a lot of read access, can cause low FPS because need to decompress and process every file. (Some games read and leave all in RAM, and in this type of game aren't perceptible)
My MGS PO was in .CSO (around 800MB), I converted to .ISO (around 1.300MB) and I had a realy improvement in performance. Now I'm getting 10~20FPS (MGS PO is 20FPS fixed in code, so 20FPS is the maximum for this game).
I think it's relevant for this topic to use only .ISO if you want to get performance.
Anyway, I still think that my PPSSPP isn't using all my hardware, I need to test with another game.
