Broken FPS Aiming

Unity Engine

I came back from a 3 months game dev hiatus and after updating Cinemachine was greeted with a rather annoying bug with FPS aiming.

Luckily I backed up my project before updating from unity 2021.02.0b3 to 0b15 so I have loaded up the old project to verify.

Here are my settings before, with these settings I had crisp mouse movement in all directions

My new settings are exactly the same except I had to bump the speed up to 25 (I’ve just tested and this is roughly equivalent to increasing Unity mouse sensitivity to .4 and keeping cinemachine at 4) with drastically different behaviour.

Now when moving the mouse especially from center just in a circle you get massive amounts of jitter and jumping, it slides along the x/y axis and skips pixels.

Is this bug known about and a fix on the way? Is there any way I can download the old version of Cinemachine

It looks like I was using version 2.8.0-pre.1 and now I am on 2.8.1

I’ve just reverted to version 2.8.0-pre.1 on the newer Unity version 2021.2.0b15 and it has fixed the issue so it is definitely a bug introduced by 2.8.1… awkward

Is your vcam being driven in LateUpdate or FixedUpdate? You can tell by pressing play and reading the text next to the Solo button on the vcam inspector.

Hey it is set to smart update but on the camera shows late update, switching to fixed update makes it definitely worse

Can you make a lightweight repro project and log a bug for this?
