It got out of the black screen fine, just a bit long, but when I got in, it looked weird, so, like you said, I waited. It did not stop unfortunately, and lag was very bad, yet I was 1 of 3 on the server...
It's not my PC, as I could run it fine before, on high, and I can run Cry Engine 5 as if it were nothing...
I'm going to try again, but if this happens again, what would you (the devs) suggest?
EDIT: It worked fine when I joined a new server.
