Why PPSSPP runs fast on decent hardware meanwhile other PSP emus are slow?

[xZabuzax]

Geez Nezarn giving up so soon? i would have loved if DragonNeos responded me like that so i could get in fighting mode a bit. The only thing that stopped me from bashing java in this thread is because i don't want to bring a flamewar in here. But it seems that DragonNeos doesn't mind a bit of a fight, right?

Since the other guys already gave you an answer i believe i don't have to respond to this anymore, but i'll add this bit, PCSP is not as optimized as PPSSPP. Once PCSP gets more optimized you can bet that it will be faster than jpcsp.

If people are going to respond to questions like this, at least give evidence and details. A response like Nezarn's implies a lack of knowledge and may lead to others being misinformed about JPCSP/Java.

Again, i would have loved to respond to this but you already responded your own question...

It is a know fact that java is slow (specially for emulators), it's also a fact that jpcsp is slow because it's coded in java and PPSSPP already proved that a well optimized C/C++ will be faster than jpcsp any day.

If PPSSPP and jpcsp have the same compatibility what emu would you choose? the faster one or the slower one? yeah, that's what i thought.

That's java for you.
