[2.0.55] Multiplayer rubberbanding

[KynnVyr]

What did i do :
since start of space age i'm hosting a headless server (debian VM in proxmox) - we played it with a friend without issue
The server don't have any mods
stopped playing for 6 mounth rougly
started playing again on this same server today (after updating it)
We both have the same PC (see logs for details)
I tried with and without Vsync (also true for most of the graphics options)

What happen :
"Randomly" the character rubberband, reproduced easily
The server seems ok (looking at the production continuing smoothly and the bitters attacking us just fine)
no FPS / UPS drop, i observed UPS even climb to 70-80 while fps stay the same but could not reproduce it

When playing solo there is no rubberbanding effect, the character move fluidly

Reproductions :
while not the only source of the rubberbanding, shooting or even pressing the space bar give the same effect
We both reproduced it on our servers or on other public servers
connecting to my server directly through LAN give the same result
creating a new game give the same result
Hosting the game on my computer i don't have the issue but my friend get it

Some video taken with the debug overlay :

Looks normal, you start over 30 ticks behind the server after joining and when you are shooting you are leaving latency hiding so you are effectively playing with half a second input latency until the server tightens those values.

Thanks for your reply,

I got back to testing again, on 2 server, my own and on another public one
after 5 minutes on each server i tested it again, the rubberbanding effect is still there

I saw some posts talking about shooting needing server authenthification causing the rubberbanding, but again i can't remember it being THAT bad some mounths ago. (my friend and i are ..... pretty chaotics, we like to go mano a mano with the bitters so i think we would remember it)

And it still is happening tottaly randomly (that i can't show for obvious reason) every couple minutes.

Thanks again for your reply

The random stuff sounds like packet loss. The rubberbanding when shooting is generally normal and from what your videos show it looks manageable once latency drops below double digits. Maybe you did not notice it before because your latency to the server was better.

thanks for your reply, we'll manage like that so
