not using multicore and GPU (Tegra3) optimazation ?

To the OP,

What geigermuller said it's true, but with a caveat.

For certain problematic games like Tekken 6 and God of War, CPU usage is a big.big problem, even on the PC, with its exhorbitant CPU usage. The GPU is not even a factor at all, it's barely touched when running those games on the PC.

I find that PPSSPP is GPU limited on games that run well on the PC, for example in Monster Hunter Freedom Unite, where Turbo VPS is only as high as your GPU can process the frames (300-400 VPS) but CPU limited in problematic games. The problematic games can be fixed to not clog up the CPU in time.
