[Discussion] 60FPS patches for PSP games that run at 30FPS

Could also be another timing issues, PPSSPP is far from being as slow as the real hardware and some games behave weirdly when programmed in a lazy, timing dependant manner. In both cases it could be patched via cwcheat, but in the first case it would not be an emulation bug.

Also there's a possibility just increasing emulated CPU clock would stop the FPS from dropping as it might simply be too slow to run at 60fps in that scene with default clocks.

Congrats on the promotion, i can certainly see why. You were again absolutely right, i changed cpu clock from "Auto" to 333MHz, and all drops are gone, it's rock stable everywhere now ( well, if i wildly, and i do mean wildly, rotate and move the map at the same time it drops to 50fps sometimes, but i think it is safe to conclude it's the clocks again) Thanks again!

PPSSPP 1.12.3 windows. 12700K/3080Ti

Change the option in the picture.
