Well, the title says it pretty much, got problems while watching Twitch.tv streams, videos constantly suffer from buffering without using anything that can cause slowdowns in my network. Streams work flawlessly in windows7 without any buffering and lag, I also tested on my smartphone if there was any issue with my ISP, and as expected it played as good as in windows7, no bufferings. I actually disabled windows updates for avoiding the well known bandwidth usage in background, so It seems the Network preferences were modified by M$ in comparison to previous versions.
