This was my attempt to create a a SNES to Bluetooth adapter. It works but the average latency was 18.35ms, which I think is too much to be considered a good controller.

18.53ms is imperceptible to humans.
I think the concern is the stack up you get in latency between the controller, the computer, and the monitor.
That’s a valid concern that I didn’t consider.
I can absolutely notice a frame of lag at 60Hz. Good way to compare side-by-side is by using an emulator with run-ahead mode.
I read that people who play a lot of FPV shooters have higher than average reaction and perception time. 18ms is ridiculously fast though, I’d be surprised if someone could consciously register it. I know gaming monitors market latency in the 1.5ms range, so maybe elite gamers can perceive the difference. Someone else pointed out that there are concerns over latency stacking between all of the devices, and that’s a really valid point.
18ms is okay but for a lot of retro content, it’s running 60fps. That means it’s one frame is 50/3ms, aka 16.6666ms. Sub 1 frame is good enough, 18ms is not in my opinion.
I don’t play shooters, but I love both 2D and 3D platformers, where you can absolutely notice a difference.
