Picade buttons input latency


I have bought a picade last november, and only just go around to build it this week.

Everything went very well, however, I can’t help but notice a significant input lag with retropie (I installed 3.8.1 on an RPI 2).

By significant latency, I mean something along the lines of 100ms between a button press and an action taking place in the game. This basically render any unplayable.

At this point, I am unclear if this is a problem with the pcb firmware (I have a blue pcb), or a problem with retropie itself.

As anyone encountered this issue before?


Have you updated the firmware since setting up your Picade? You can find the latest, including instructions, here: https://github.com/pimoroni/picade-sketch
