smoothing-addon VS realtime-network-sync-godot

I have been tearing my hair out trying to figure out this issue. This problem seems to have come up suddenly, but I'm not sure where I went wrong here. I don't think it's a physics related issue as this plugin (https://github.com/lawnjelly/smoothing-addon/blob/4.x/README.md) doesn't seem to help.

Speaking of smoothness, are there any plans to somehow integrate lawnjelly's excellent smoothing-addon to Godot core? In my opinion pretty much every game needs to use that addon.

I've found that there's an addon for 3.x and 4.x that adds physics interpolation, which is great, but it's clunky to have to introduce another node for every visual physics object, as well as having to rework the scene tree since visuals can no longer be children of their parent physics objects. I've also discovered that it fixes large jitters but not small jitters, which seems like an improvement until you set your max FPS equal to your physics FPS, and realize things still can be SOOO much smoother.

There's a smoothing addon that can help with this issue, in my personal projects I've just been using this since I'm not currently using rigidbodies.

But, you mentioning the sprite moving and not the CharacterBody2D inspired me to dig into my player scene more and found out that the "Smoothing2D" addon I was using was the culprit (https://github.com/lawnjelly/smoothing-addon/issues/31)

The smoothing addon by lawnjelly has a 4.x branch so you can use it: https://github.com/lawnjelly/smoothing-addon/tree/4.x

in 3: enable physics interpolation in editor settings in 4: download lawnjelly smoothing addon for 4.x

4.0 doesn’t offer physics interpolation from what I can tell, at least for 2D. Try this addon, it works for 2D and 3D and I’ve heard plenty of great things

There was some dude who used the Tribes networking model (still really the gold standard for this kind of thing) here: https://gitlab.com/Juankz/realtime-network-sync-godot but I haven't tried it out.
