I’ve had the problem of microlags/-stuttering and rubberbanding for a few months now, although I have no packet loss and a low ping (40-50 ms with WiFi, since I don’t have an Ethernet connection in the room). I am sometimes pushed back and forth by the server, the weapon sometimes changes to the old one or I can no longer precisely select the nate I actually want, even if I move my mouse wheel only slightly.
I wanted to look for solutions, but the subreddit is currently not visible and so I had to register here.
It does indeed, I’d really try getting an ethernet cable and test from there. just run one long cable for the sake of testing from the router ;)
