Jerky camera with Orbital Transposer on rigidbody target

We have a top down (ish) game where the player can rotate the camera using the right mouse button.

This is how it looks like:

We have a Cinemachine Virtual Camera set up like this:



The Look At & Follow are both rigidbodies (these are the player, both are set at runtime). The Cinemachine Brain Update Method is set to Fixed Update.

Whenever the game is played at 60FPS, the camera behaves fine. Rotation is smooth and remains smooth when the player walks. However, in a build the FPS easily hits 200+ and that's where the problem lies. When you try to rotate the camera, it is very slow and feels sluggish. If I set it to Smart Update, the rotation is smooth, but when you start walking it looks like the character stutters (it's not actually the character stuttering, but the camera not updating and then jumping back to catch up I guess).

I'm not sure how to solve this problem, as all my attempts have either resulted in my first issue or in the 2nd issue. Right now the only "solution" we have is locking the framerate to 60, which we don't want to do.

Does anyone have a similar system who can share their result?

 

I'm also noticing this issue. I tried what you recommended, @Gregoryl (see snippet below), but there is still jitter when using an Xbox joystick, albeit a smaller amount. I've also tried switching the Update Method property on the Cinemachine Brain but to no avail. Looking at Cinemachine's AxisState.cs's Update function, it seems like deltaTime is already being taken into account. Any other thoughts? Or should I file a bug?

My snippet which I've tried calling in both Update and LateUpdate:

_orbitalTransposer.m_XAxis.Value -= (rotateDelta * rotateSpeed * Time.deltaTime);
