Buffering issues on Windows 10

I’ve been a Plex user for many months, and until today, had not had a problem with it. I just got a new computer, with Windows 10. My old computer had Windows 7, and everything worked get with Plex. However, with the new computer, I have terrible buffering issues when trying to stream things on my Roku from my computer. I tried a file that I had watched via my old computer with no problems, and it is having terrible loading times and buffering issues.

I checked to make sure Plex was being allowed to pass-through the Windows Firewall.

I would like to request some help. Thanks in advance!!

It would be great if you could supply the server logs https://forums.plex.tv/discussion/25417/where-are-the-pms-logs-on-windows#latest as this will help us figure out why it’s having issues supplying the file fast enough to the roku.

Normally it’s because the roku is configured at too high a quality, and bumping the local settings down will fix it, but lets take a look at the logs first!

Here you go. I zipped them all up. Thanks for taking a look!

bump I upgraded from windows 7 to 10 same issues.

I am probably going to go back to windows 7 to see if it helps all I use my PC for is using Plex as my media center for my Roku anyway.

rossdargan, did you have a chance to take a look at the logs yet? I’d really love to figure this out. If you need more information, let me know.

It’s been almost a month since I made my initial posting. Is there ANYONE out there that would be willing to help me? I have no idea what to do. Everyone was great under Windows 7. Now with Windows 10, the buffering issue is horrible.

looks like your missing a file… wheres the file named Plex Media Server? should be one without a # extension.

Thanks for the reply.

Hmm. Not sure how that would have happened. I zipped all the files that were in the Logs folder. Weird.

I decided to delete ALL the logs, reboot my machine, test Plex again, and have it create all new logs. I’ve attached those. Before I created this ZIP file, I exited Plex, in case that made any different.

I did a test with an episode of The Flash, and the buffering problem is still there. It played fine for 2-3 seconds, and then stopped and buffered for 4-5 seconds. Played fine again for 2-3 seconds, and then buffers again. It just repeats that over and over. No idea what is wrong. I have the same exact setup as I had before. It seems it is either the new computer and/or Windows 10? I am running Windows 10 Home, 64-bit.

Bump. Anyone?

This definitely feels like a Windows issue. I’m able to rectify it if I run a torrent on the same client that’s having the buffering issue, to my amazement. Like some kind of stay alive connection issue?

Has there ever been a resolution for this? I am using Windows 10 with Plex media player, and there is terrible buffering on it when streaming over internet. It is not an internet speed issue, as I am able to stream the same file using Nvidia Shield with no issues.

This, suspiciously, feels like a Remote Quality issue, more specifically the Remote Quality setting in the Plex Media Player app. Not sure what the default setting is for PMP, but for everything else it seems to be 720p @ 4Mbps.

If that is the case, change that setting to Original (or something that would exceed the bit rate of the material) and try it. Shield is great at Direct Play, but so is PMP. A Transcode is probably the reason for the buffering - in my opinion. Try to determine if that is what’s happening.

I am able to play 4K media with my shields, with no issue, yet when I play a file that requires anything above 10 Mbps to my windows 10 pc, there are buffering issues. If I reduce the quality to 720, it plays fine. My point is I should not have to do that. There is something slowing down the speed when o am using Plex player (or Plex Server) on my PC. Also note that the outbound signal from my Plex server on my LAN is fine. No problem playing any size file in that direction. O have Plex Pass as well.

I am also having the same problem, although my issue is both on remote streaming and watching on devices attached to the same network as my server. Plex Media Server was working perfectly on a machine running Windows 7, but on a new Windows 10 machine the loading is so bad that I cannot watch anything. I triple checked my settings and even had a friend that manages a network for an office of over 100 take a look for me. Everything appears to be set correctly, but still nothing will load correctly.

Has anyone made any progress here? I have been running plex on Windows 7 fine for over a year (or more), no quality or speed issues in transcoding to Panasonic TV Plex App. Since Upgrading to Windows 10 it’s unwatchable. Constantly buffering. I have been trough forum after forum trying a bunch of different recomendations with no luck. Seems only to be an issue when Transcoding is necessary. Not an issue on Android TV or Iphone that do native/original playback. I’m possitive this is a Windows 10 problem as it only started once I upgraded.

Having MAJOR issues the same day that I upgrade to Windows 10.

Windows 7 = No issues whatsoever

Windows 10 = Buffering until Frozen

Been using on Win10 since day one w/ no real issues. What are your specs for these machines? I have an i5 3Ghz, 16Gb ram plus a video card handling everything. Make sure that when you update…that you also check that your video drivers and such are all up to date as well.

My Spec are i7 3.4GHZ 32GB RAM, SSD HDD. NVidia 1060, with Latest Drivers as of Yesterday. I’ve tried disabling LSO on network interfaces. No effect. I’ve tried every option i can find to no effect. I have tried a plex repair (not full reinstall), and updated to latest version… i’m running out of ideas.

Also forgot to mention when the buffering is occuring both plex and PC process are using less than 20% CPU and barely any RAM.

Side Note. I have created a VM on the existing Windows 10 (4 core 4GB RAM, Bridged Network) PC Running Windows 7 and reinstalled plex there and mounted the existing drives in. Everything seems to run perfectly again. So it doesn’t appear to be a resource issue. From my experimentation I think it’s something to do with the Windows 10 Network stack but I can’t figure out exactly what. Not willing to spend anymore time at this point. Next step might be a Linux VM given Windows 7 is out of support.
