But if it's a 444 Mhz clocked ARM device with dedicated PSP hardware for its built-in emulator, then hoping for 2x PSP resolution doesn't sound very likely.Įven if it can be clocked up to 2 Ghz, PPSSPP currently has tons of problems specifically on PowerVR SGX543 (the GPU Vita uses.) Some seem like OpenGL driver bugs, but I'm not sure how capable it would be for some of the trickier effects. Given that, PPSSPP may not be able to bring a lot to the table.
I wonder if it contains the PSP's GPU as well, because if so that would easily explain how it can run well on PowerVR. If that's the case, performance will probably not be great.Īlso, from some educated looking Twitter posts, it seems that the Vita includes a MIPS processor - and runs PSP games on this processor. I've read contradictory information about the CPU speed of the Vita - it sounds like the hardware is capable of more, but it may be locked to a max 444 Mhz.
