Why is my mouse always lagged?

Are your mouse drivers up 2 date, make sure they are otherwise it could cause those issues.

Buy new mouse....
Install drivers...
Viruses? :lol: :lol:

its eventually the sensor if you have an old or cheap mouse then its obviously the mouse so buy new one i could recommend the Steelseries Rival 110 cheap and nice sensor or its the mouse bad.

I would suggest you get a new mouse, or if it's wireless, it could be that the battery is low

test it on another mouse, if it lags - hardware problem, if not - mouse problem

Your mouse is lagging cause it's bad get a better one maybe? lol i have a good one it was like 5 lol

if you don't have a mouse pad get one right now... if you have a bluetooth mouse or a really cheap mouse there could be a bit of latency between screen and mouse movements...

if its a wired or wireless mouse (wireless being it uses a wireless usb receiver) try using a new usb port... (if its hooked into usb 3.0 or 2.0 try hooking into a normal port... thats what i have to do)
if its bluetooth then that will perfectly explain why it lags as its just using radio waves to send and receive.

If you have any other questions just ask

Check with the machine's maker or motherboard maker to see if they had a driver package for the motherboard and USB?
