I bought a Pi 3 a while back with some cheap SNES controllers from Ali Express. After setting RetroPie up it worked wonderfully, except that the controller latency is very high and makes a lot of action games like Tetris or any shooter impossible to play.
I know that my controllers were extremely cheap and probably quite low quality. I'm happy to spend a little extra getting some better, newer ones, but I'd like to know if it's actually going to make a difference or if all USB pads will be laggy and unresponsive.
Will a better controller fix my problem?
