PPSSPP much better on much worse phone (XPERIA NEO V vs XPERIA J)

[Majkes]

I am able to play Locoroco in 60fps on my almost three years old xperia neo v. It has one core cpu and ridiculously low ram. Recently I acquired new phone, xperia J, which has a single core processor, more ram, better graphics etc. But the game works terribly, even with the same settings (except for enabled multithreading). I've tried every combination of setting and the performance is still around 15-20fps with very laggy sound. WHy is that, why is so much better device giving me much worse results?

the emulator performance varies on certain smartphones, regardless if they are older or newer model. Probably the new Xperia has some features that may affect the performance of the emulator.

It seems like GPU driver quality is a bigger performance differentiator than specs on Android... annoyingly enough.

Also, how can you use multithreading with single core?

You can't. one core pair tread.

RAM doesn't mean much, and xperia neo v specs are better than xperia j, adreno 205>200, Scorpion>A5

The Xperia Neo V has the same hardware as Xperia Play, so I think the performance is the same, or nearly so.
