Question Mouse Polling Rate- Difference Between 400-500hz

[The Guy From The Thing]

there's a clear discernible difference between 125hz and 500hz, at least to me and most people. but is there really any noticeable difference between tighter number ranges like 400-500hz? or even 300-500hz?

I ask because moving my mouse side to side doesn't produce an exact 500hz, it fluctuates between 400-500, and I'm wondering if this actually has a noticeable effect on smoothness and in-game cameras. when the polling rate is low, like in the 100-200s in Roblox, I find the camera to be quite choppy in comparison; in games where the polling rate would be within that 400-500hz range, the camera is definitely not choppy but I'd like to know if there is any discernible difference here


when I move slowly and pan the camera around, I can see somewhat noticeable breaks but I really cannot tell if that's just my slow-moving fingers/hand causing a sensitive movement on the mouse, or if there's like an actual clear difference in the 300-500 or 400-500hz range

I have an Atrix Guild mouse which is 500hz max

The cycle time difference between 400 Hz and 500 Hz is 0.005ms. You're not going to notice this.

Even then, the polling rate is simply how often the mouse sends data to the computer. Whether or not the game is processing input at that rate (it likely isn't ) and if this rate lines up nicely with how often input gets processed can play a factor.
