Sounds just like my gameplay when I have Netflix going. Im on a 15mbps package with Teksavvy and basically all internet streaming usage has to come to a halt in the house when I play.
Other than that, when I played yesterday I had no issues. I was under the impression this game was designed when people were still living the 56k dream, so why I can't play Netflix and game online the same time is beyond me. Maybe it's an upload speed issue with you, in sending info to the server and receiving it back (delay between your click and what you see happen). It certainly is with me (when streaming).
Was anything else making use of your bandwidth?
