RE: Guide:- Maximizing the performance of PPSSPP on your Android/Windows device.
There's a super easy way to tell if you're GPU or CPU limited.

Turn frame skipping up to max and disable auto frame skip.

If your FPS goes to 100%, and audio sounds smooth (the graphics will obviously be terribly choppy), then you are GPU limited. Frame skipping does NOT skip the CPU emulation, only the GPU emulation.

If it's still not able to play the audio at full speed, then you're CPU limited.

That's it; it's easy. It's hard to argue with the fact that frame skip only skips graphical operations (though this includes the driver, etc., which runs on your phone's CPU.)

But yeah. For some weird reason, PSP game authors made the very strange and bizarre choice of optimizing their games for the PSP fixed function hardware, rather than optimizing it for OpenGL ES. Go figure. I guess that's weird in the same way that Android games that run well on tablets are strangely optimized for OpenGL ES, instead of being optimized for the PSP graphics chip. What can you do with game devs? If only they would build their entire business strategies around emulation, right?
