I've been using it for a long while now...and it is finally ticking me off. What is with Windows 10 and awful streaming video performance on certain sites? And before you say anything: -Same LAN/router/modem -Same ample bandwidth to work with (30 megabit) -Same website (Eurosportplayer, specifically-they're the only tools left streaming Silverlight BS) -Same wireless connection -Same video quality selection -Same (if not similar browsers) Windows 10 rig is my sig rig in this test (i7 and GTX 980 with latest drivers every time I've tried) Windows 7 rig is a cheapo Lenovo laptop with I think an i3 and integrated graphics Windows 7 will play Microsoft Silverlight video just fine. Windows 10 will not. I've tried Opera, Chrome, Internet Explorer, and Firefox....the trend is the same. W10 is unusable, video seems to buffer/freeze every 3-10 seconds (varying on browser) for 3-5 seconds. Windows 7 plays it fine-all browsers. Shoot my sig rig played Silverlight Eurosport fine before switching to W10. Anyone know how to fix this, from what I've read it has been an issue on W10 from Day 1 of RTM?
