Latest update to Windows 10 is the "Fall Creators" version. As the previous version "Creators" has been brilliant, I forced my computers to load it.
Everything seemed fine ...... but, videos were lagging (audio/video sync problems) and getting a bit of interference on the audio. Memories from the old Adobe Flash problems we used to have, except these videos were HTML5 and don't use flash, its built into the browsers.
Initially I blamed it on the latest Firefox update but further examination (using latencymon) showed it was a system problem.
USB and TCPIP drivers (both are microsoft drivers) were taking up way too much time. Reverted back to the previous version of Windows 10 (creators) and now videos are fine and latencymon shows no huge delays.
While I'm not using an amazing spec machine, its a 3GHz Core 2 Duo with 4MB ram, it shouldn't be struggling. I've yet to check if my laptop has the same problem.
I hope Microsoft fix this before the Fall Creators update is forced on me but I can't find other mentions of this problem on the internet for this version of Windows.
