PPSSPP - Samsung Galaxy S6 Edge+ progressive Slowness

[TkSilver]

Best case scenario would be one thread per each emulated chip or part of a complex chip (like the PS2's emotion engine), but in reality even if cores share cache and other reasources it usually ends up with a performance decrease not an increase. There can be performance benefits for offloading emulated gpu code onto a real gpu over a CPU core, assuming that you have an api capable of handling the correct functions.

As far as the S6 goes and specifically the process scheduling, that is handled in android by the governor. I would highly recomend you do not screw around with this unless you.... A. Know what you are doing B. Do not mind screwing up your over $500 smartphone to get a few extra fps in an emulated psp game C. Understand the simple idea that the people who spent millions to develop the device in your hands probably have a very good reason it is set up like it is (usually battery life and heat) and changing core things like the governor can cause your battery life to drop like a rock or your phone to damage itself with heat. (If you were going to tweak it to perform slower there woukd be less worry and risk asides from screwing up and permanently bricking your phone)

If none of these things bother you then the XDA forums for your specific device will be the best place to get more detailed advice.
