I have a corsair M90 mouse (MMO gaming mouse, yeah yeah )
It used to be wonderful, has loads of different buttons that I have a bind for, and they used to be super super responsive. But lately they have become disgustingly unresponsive, only picking up the input sometimes, or having a big delay between button press and actual input. I'm not sure what could be causing it. Everything else about the mouse is absolutely fine.
Has anyone experienced anything like this before?
