Why have no one ever told me about mouse polling rate!? This makes mouse as smooth as a joystick!

I never considered buying a "gaming mouse" because what could be so special about a mouse? So I always used cheap generic mice and never felt the need to buy a gaming mouse until recently I bought one just for the looks and it's almost like experiencing 60fps for the first time! People buy gaming mice for high dpi or ergonomics or high polling rate for better aiming, but there's one more benefit of a high polling rate that alot of people might not be aware of. I prefer to play with keyboard and mouse with vsync so I get perfectly smooth frame timing except when I move camera with mouse, even at 60 fps, camera panning looks jittery with mouse but not with a controller.

Whenever I looked this up on Google, the answers were always that that's just how a mouse works. But the real reason that happens is because most people have mice with 125hz polling rate, since polling rate is refresh rate of a mouse so the higher the polling rate, the smoother the mouse movement will look. I know the real purpose of a higher polling rate is to reduce input lag but smoother visuals are an overlooked benefit.

So long as your polling rate is double your frame rate, Nyquist-Shannon theory tells you it doesn't make a damn bit of difference.

That's why we settled on 125 Hz, because it's more than double 60 Hz.

You should be aiming for around 250-500 Hz today, there are mice much higher than this, but they generally use image interpolation to send back fake updates.
