I am having the same issue. I don’t think it is my ISP because my boyfriend is playing just fine a few feet away from me on the same network and router. The diagnostic scan shows packet loss at Denver and Dallas, but so does my boyfriend on his computer whose game runs as smooth as butter. I cannot replicate the packet loss elsewhere. Tests from pingtest.net to Dallas show good ping, little jitter, and no packet loss and I seem to not be having issues with other online games. My game used to run very smoothly and this seems to have started a few days ago, shortly after the last patch. This may be a coincidence… not sure.
Any insight? I miss being able to (reliably) play
