That said, Fat Princess seems to not go full speed for me (although close) and it's because of the VFPU AFAICT. That's because the VFPU isn't really jitted yet. My recent changes have improved its speed slightly, and improving it more won't be hard.

For comparison, based on a profile of Fat Princess (on my ivy 3.4Ghz / 9800 GT), moving the GPU to a second core has the best-case potential to save 10% (as current), and probably not that much since there's overhead with multicore.

In contrast, properly jitting vmin, vmax, vmov, and vneg has the potential to save at least 10%. Overall the game is spending almost 40% of its time in the VFPU, which is significant, and much more time than it's spending with the GPU. So for this game at least, VFPU jit would be much more important than multicore AFAICT on Windows.

On mobile, can't know without a profile. It can vary by hardware and platform.

Games that aren't running full speed on my PC are: Fullmetal Alchemist Brotherhood (about 45-50 FPS, mostly 50 FPS), Gundam vs Gundam (40-60 FPS.. It drops to 40 when some robots activate some big circles all over field.. All tought it runs 55-60 FPS when no circles).. Haven't tried NBA 2K13, so i can't say how much it would run on my PC...
My specs are:
CPU: AMD Athlon 64 x2 3800+ 2,30GHz (OC'ed)
GPU: Nvidia GeForce XFX GT 240 512MB GDDR5 (OC'ed, but FPS on PPSSPP are same when it's stock)
RAM: 3GB DDR2
OS: Win 7 Ultimate 32bit
I belive this PC should be good enough to run PPSSPP properly.. Maybe not at the moment, but later when speed improves. What do u think?
