VR Expansion Plugin

Oh, that is an entirely different thing, and no it isn’t caused by the plugin. It should be more apparent with fast jerky side to side movements when using TAA (actual ghosting) or at low framerates (jerky).

Lateral movements don’t actually adjust the apparent scene as much as rotational ones do, and mouse / direct rotation can be significantly faster than manually turning in VR. I assume you are driving the rotation by DeltaTime too, as you would need to do that.

The car doesn’t turn straight on axis, it turns over time smoothly, also while in the car you are still using the same camera…

If it was VR specifically related you wouldn’t see it in 2D, the late update pathway isn’t used without an HMD being used and tracking.
You asked originally about networked turning, which doesn’t have anything to do with actually.

You’ll notice the same thing in the FPS template as well, although I haven’t seen it as bad as you are showing, you have either really bad framerate there or are not driving it correctly.
