Heya! A shame that my first post regarding Rust is in a 'bug report' but like you said above, alpha is alpha. I'm having the issues as you guys, this will happen on servers with 0 - 199 people with pings ranging from 40 - 200 neither seems to affect the rubber banding.
Specs,
ISP, Century Link 5M down 1M up
Mobo, MSI 870a fuzion
CPU, Athlon II x4 @3.6
GPU, ATI 6950 2gb
I have a friend of mine I play with whom uses an ASUS board with ATI graphics and doesn't have any problems when playing albeit receiving graphics anomalies and fps drops because of his wallet capacity he doesn't seem to get latency lag, and I am, and I'm using an MSI manufactured Mobo. I'm guessing that correlating ASUS boards with ATI graphics causing the issue wouldn't be entirely accurate. if there's any more hardware/networking information that would be helpful I will gladly provide.
I think this is about all we can use at this point to pinpoint that it's not just an ASUS problem.
It must be older hardware seeing as most hardware now is DDR3 mobos on the socket AM3 / FX sockets as well as LGA 1150 sockets for most people.
It could potentially just be older hardware, but I'm starting to think it's some kind of installation gone wrong somewhere in the files and we're just getting the shortest straw on it.
Hopefully there will be an update that fixes this shortly, I'd like to play this game without desyncing as it's a beautiful game and very very fun.
