Hello. I am a happy owner of a fast bluetooth keyboard called Designer Compact. Typing on it is a blast and thanks to its fast response times it is suitable for gaming too. But that is how it was on windows. After moving to Linux I noticed that its inputs became very inconsistent. Say if you spam a button to move forward with exact same intervals there is either a delay on the press or the release of the button, or no delay at all, and this is obviously not good for gaming.
I have already tried and checked many things. All needed firmware is installed. I though, maybe it doesn't get enough processing (which would have been funny if that was the case) so I set its priority to -20, but no use. I tried setting up ControllerMode to le but it made inputs even more chaotic. Setting KernelExperimental and Experimental to true had no effect. Configuring MinConnectionInterval , MaxConnectionInterval and ConnectionLatency didn't help as well.
I will share some details below so there is something to work with.
$ inxi -Fxz
$ bluetoothctl
$ hciconfig -a; sudo dmesg | egrep -i 'blue|firm'
$ sudo systemctl status bluetoothThanks.
