New emulation method to eliminate input lag

[mediamogul]

@pjft said in New emulation method to eliminate input lag:

I was hoping there'd be a stable "default-ish" setup that would work for the majority of cases in each system

A setting of '1' should actually be stable across the board, barring 2600 games. Anything more in many games will alter your timing in the opposite direction as latency and even create artifacts, such as single-frame 'game over' screens and sprite interactions that shouldn't carry over from your actual input. Still, a setting of '2' is only adding one more frame and it's possible that artifacting would rarely be noticed.

I'll dig into that in the coming week

Let us know how it goes.

Hey guys how to I enable the latency features for just some emulators. Do I need to setup custom emulator config files or is there an easier way to do this through the gui.

You could enable it for individual systems by adding

run_ahead_enabled = "true"
run_ahead_frames = "1"
run_ahead_secondary_instance = "true"

to /opt/retropie/configs/chosen-system/retroarch.cfg above the #include line

Excellent, thanks a lot.
