Ue5 jittery/choppy mouse camera input during movement (Default ThirdPersonCharacterBP)

Yo’

I found this thread while also looking into this issue in my game, I think I have found underlying problem, which may give people some insight into how to fix it.

Example - Your goal is to move your mouse to the right by 1,000 pixels

  • If your in-game sensitivity is 1, your reticule will smoothly pass through each of the 1,000 pixels.
  • If your in-game sensitivity is 5, your reticule will jump 4 pixels each mouse step, and you will only hit 500 of the 1,000 pixels.
  • If your in-game sensitivity is 10, your reticule will jump 9 pixels each mouse step, and you will only hit 100 of the 1,000 pixels.

This issue will unlikely be observed if your mouse DPI exceeds 1,200, as most will lower the in-game sensitivity. You will see this issue often if your mouse DPI is around 400.

There could be something in the UI that captures high-precision inputs and outputs them at a lower resolution.
