When trying to use the joycons as xinput (to play in cemu for example), it connects successfully but there is a delay in response when I press buttons. Is this something I can try to fix these kinds of lag issues? (I'm using a bluetooth adapter and I'm sitting very close to it)
P.S. I tried connecting a WiiMote with wiinsoft and it worked flawlessly without any lag.
I've experienced this as well and I'm not sure what the issue is. It was especially noticeable with the right Joy-Con unless I was holding it with just a few inches of the dongle. I was wondering if it might just a firmware issue since I would occasionally get it on my Switch as well and was hoping it would be fixed with a future controller update.
