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. Also checked: forums.mydigitallife. info/threads/70328-Quick-Links-to-popular-posts-on-MDL-and-other-sites-amp-FAQ-s/page4?p=1262501&viewfull=1#post1262501 and it didn't solve anything.
Try to disable the Windows Media Player Network Sharing Service, see if that improves anything. I noticed when i play streams with a sniffer program that this service creates a lot of traffic.
Thanks for answering but it didn't work, also as additional info, it doesn't get any buffering when playing streams in High Quality, just in Source... so the thing that is driving me nuts is that just happens in W10... still no problem on my smartphone and W7.
Try disabling flash so that the new pure HTML5 service gets loaded. While it's still beta, it's in a good shape and should work flawlessly in most cases. Maybe it'll solve your issue, but even if not, your CPU and GPU will thank you for the lower resource usage.
Does this happen in all browsers you have tried? You might try using TCPoptimizer using optimal settings for your network adapter(s) to see if that helps.
if you don't find a solution you can use livestreamer.io with vlc or some other player, takes care of s**tty ISP and windows 10
if you disable, windows updates, windows defender (updates too), all the spyware/malware that 10 has, what do you have?. 7. So, its clear.
if you have amd video.. run DDCU and reboot then device manager. update the driver. amd streaming issues are common
Thanks everyone for answering and trying to help, im using a nvidia gpu and tried 2 browsers, Vivaldi and Chrome both based on Chromium so it didn't make any difference, I know there are many workarounds to my issue such as VLC using Livestreamer, but it is kinda sad to have such problems just by changing the OS, it is the same setup as I have in W7, these small problems make me think in sticking to Windows 7 till the end of the support... EDIT: Okay, after testing for 2 hours using TCPOptimizer as MacAddict01 suggested, is working properly now, it seems like Microsoft has messed up some Network settings in comparison to windows7.
