VPS or FPS,which one should I be looking at?

VPS = Indicator of your system's performance on the emulator. If below 60 your system is struggling for that particular game in the emulaor.

FPS counter in PPSSPP = Internal measurement by the emulator. Consistent numbers that are unchanged, irrespective of your system specs. Can be either 30 or 60. If below 30 (e.g. 20) the game has internal slowdown issues. Use the CPU speed hack to rectify this problem until it can fixed by the devs.

VPS counter is the more important one to look out for.

FPS counter variances indicates an internal emulator problem with the current game. (e.g. slowdown, wrong GE timing etc.). Has nothing to do with how powerful your system is.
