I've tried a controller test. Seems the controller in general can be EXTREMELY laggy and unresponsive to most inputs. It also holds almost all inputs for a full second, as if the controller itself runs at 1 frame per second.

I think I have a theory on why this is happening

On my previous test run, it ran perfectly well with just my Switch 2 Pro Controller. Usually, I have my Switch 1 Pro Controller in case I need to play something else that has the Switch 2 Pro incompatible, mainly non-Steam related things. This time, I had it off and it ran perfect for 3 races with no sign of lag.

ruse the beta version of steam you will find in interface ive had no issues with mine since doing that

i’ve had the same issue even running on the steam beta client, the only way i’ve figured out to have it work consistently without inputs lagging or my stuck input being the only thing it senses is using the controller in enabling tool mode basically dev mode as it lags 5 seconds behind when i do multiple inputs very quickly, but when i do dev mode it’s seamless and perfect. has anyone found any fixes yet? because the only way it connects through steam is in beta mode but has these terrible input delays.
