Keychron M3 Mini lags?

Hello there!

I mostly play CS, so for me mouse stability is utterly important.

After 3 month of using M3 Mini, the mouse is loosing it's smootheness in mid-game, it is starting to lag, more like skip/jump when I turn the mouse left or right. It made the game unplayable.

I monitored and found no FPS spikes during the game.

I have a good gaming PC which can run Crysis on high quality.

Any advise on this issue?

Thanks in advance!
