please provide more information, what game is only getting 12fps?
just because you can use pcsx2 full speed on some games doesn't mean anything (esp if you use speedhacks) (for example nearly anyone with a sse2 processor can run the game Odin sphere at full speed under pcsx2 since its mostly 2D, but when they try a game like killzone,Primal, zone of enders or shadow of the colossus they quickly find out these games can bring any pc to a crawl even top of the line.), the same goes for Jpcsp (or other emulator) it depends on the game and compatibility status and the overall speed of your computer, some games will work better then others since more testing has been done with them as-well as other factors like how the game was programmed.
from what I've seen in your post most slowdowns would point towards the Intel GPU since they were never intended for heavy 3D gaming, the CPU is decent and you should have enough ram
