Yup Only this worked for me , I went in Character and disabled “Orient Rotation to Movement” and it worked like a charm , Thanks

it works for me too, thanks
5.2, both in selected viewport and PIE
if i press any keyboard key (and hold) AND move mouse (for rotating) then camera is start lagging.
if i dont press a key and move mouse then camera not lagging.
it happening in default blank project without any actors.
Disabling this plugin fixes the issue.

For me, Setting Camera Boom component Pre physics resolved it.
Component Tick > Advanced > Tick Group > Pre Physics

I had this problem when I had the camera as a member of a Pawn that I had set the root component to a physics enabled mesh. (whew that was a mouthful)

So I had this:

Pawn
|_ root component (static mesh with physics)
|_ camera

Once I made the physics enable static mesh no longer the root component the problem went away

It’s still happening even with this plugin disabled

I mean… this is with a blank 3rd person project… it’s quite a major issue no?

I’m experiencing this issue in 5.5. Even with a brand new first person template, the mouse stuttering is there and is really distracting. Disabling the mentioned plugins made no difference for me.

What’s weird is when I use an Xbox controller as the input, it’s suddenly buttery smooth. Not sure if it matters but the mouse I use is a Logitech G502 X Lightspeed.

I had a similar issue, and I found out that for me it was caused by glitched frame sync. I had 70-80fps on 60Hz monitor and it was shaking similar to attached videos, and when I turned on VSync, the problem was gone, even that I had actually less fps (60 with VSync vs 80 before).

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.
