I always felt the PPSSPP core to be very laggy compared to my real PSP, but never really investigated.
So today I tried a few games with the single frame stepping method (pause + k), to get the internal latency. Tried three games:
- Castlevania: The Dracula X Chronicles: 6 frames of latency
- Pinball Dreams: 6 frames of latency
- Parodius Portable (tried both the first and second Parodius from the menu): 6 frames of latency
Intuitively I would say something is off with the emulator implementation or the libretro core.
Does somebody possibly know whether this internal lag is correct or not?
