Thanks to STEAM I didn't even get Beta 6, 720 MB of 2,200 after three days. Now I start all over with measly 32.8 MB of 2,600. I like GalCiv, but with STEAM it's a pain in the ass!
Oh, yes. I've a connection with 55.000 kBit/sec, not a 300-baud-accoustik coppler.
Did I mention that I dearly love STEAM?
Interesting, I have about the same download/upload speed, ~60 Mb/s, (it's same with FIOS now) which is what you seem to have, but I download from Steam at ~7 mb/sec and get the entire game in a few minutes, patches quickly. Wonder why you are getting such poor results, that is frustrating!
I am guessing from my results that Steam may not be the problem, at least not directly. Something about your connection path to the download servers; there was a time when I could troubleshoot that sort of thing, but the tech has left me behind, lol.
