Apologies for double post, thought I should do a little testing before posting. I am having some serious latency issues as well. Just been playing for two days now and sometimes 
is showing several thousand millisecond latency. Rubberbanding has been on par with web version, sometimes worse (although that could just be my crappy memory) Adjusting graphics settings appears to have no affect for me. Using this thread I did a little troubleshooting:
I also ran
ping for several minutes on gs-beta.playboundless.com as well as gs-testing.playboundless.com (kinda a shot on the dark for that one, but I assumed it’d be different for this latest release) Got between 40 and 70ms on both when i wasn’t loading new forum pages up heh. Might it be my upload spead? Let me know how I can help. And thanks for all the hard work you are putting in.
Edit:: I am going to double check some things on my end over the next day or two. I just want to make sure that there is nothing on my end screwing things up.
