Whenever I play Osu! with a mouse you plug in with a USB ( the ones that are wireless) it lags bad. The lag I'm getting is dropped frame rate and I can't play Osu! mode without missing circles because of the stuttering and reduced frame rate. The weird part is though its only when I use my mouse, I can play taiko fine without the lag. It's only when I use my mouse. It might be because I'm playing on a laptop with a mouse or the mouse is the problem. I've been thinking about getting a new mouse to see if that helps in any way. I've done all I can on changing the graphics setting and even turning off some details for gameplay to see if that helps too and it dose nothing.
