It's so obvious that many users complain about ppsspp lagging and all
that
Phone Ram is also one of the
important
And also Phone Arm / bit
Just imagine user with 512mb ram phone trying to use the ppsspp android emulator and you expect it not to lag
That's so obvious
But with the settings below i guess it should be able to help
*Open Your PPSSPP ANDROID EMULATOR
* clicks settings
Then graphics
Check screenshots below
If your phone ram is 512mb i don't expect you to choose
ModeMode :non-buffered,faster
Choose buffering it might not be clear enough though but am sure it won't
lagAnd it will be fast
