So I got the dongle per the link below and set it as my active Bluetooth device , and I’m having the same exact issues . Fine with one controlller but second controller starts to lag after a few seconds for cemu , Yuzu. Oddly , i do not have the issue with dolphin emulator . Both controllers work without latency.
Any other suggestions ? Is it just mabye a function of the emulators and nothing to do with my Bluetooth ?
