  • Laggy Experience on any Resolution?? (Windows 10)

So I recently switched to a new PC Setup with an RTX 2070, 16GB of RAM and a Ryzen 2700X with a little hope of getting better quality in my SLR App. I also switched from WIndows 7 to Windows 10. I can definately tell that my Hardware improvement worked on a lot of programms, sadly it doesnt seem to work on the SLR App.
I seem to have a somewhat good quality video but for some reason it feels really really choppy. Back on my GTX 970, videos with 1920p were looking fine and really smooth (You could tell it had 60 frames). Now on my RTX 2070 even those get choppy.
I red something about installing Codecs like the HEVC Extension and LAV Filters. I installed those now but I have no Idea how to use them (I just assume they activate by themselves) and I cant deny it hasnt been for nothing. Before installing I got some weird Pixel stuff destroying my experience every 10 seconds. Now those are gone but like I said I am still stuck with "choppiness". Any help? I dont think my Hardware can't handle these kind of videos.
To describe the choppiness more: It feels like the video is slowing down in frame rate and catching up afterwards again with it.

I hope someone can help me. I really assume the problem is with Windows 10 on this one.

    Seriousguy98 Hey, when video plays, does it decode on GPU? you should see it spiking right after pressing play, if CPU is ramping up, you need to check if in LAV filters Hardware video decode is set to CUDA

    Let me know if you can figure it out, if not we can go step by step

    Best

      Soo for LAV Video Settings I use NVIDIA CUVID as my Decoder. Should be the GPU if I am right on that. I played with those settings a lot but none of the decoding settings really worked. The Task Manager says that my GPU is going up onto 90% for 3D rendering when playing a video.

      What I noticed tho:
      I downloaded one of the videos (5K) and it seemed to work with the default version of DeoVR Player (When using Direct Play). Using the same stuff on the SLR App seems to still make it stutter. 6K still doesnt work on either software.
      I am really bad with the decoding stuff and such and it seems like it must have something to do with Windows 10 because with my worse Hardware I was still able to watch 90FPS 4K Videos and it looked so smooth, I was almost thinking it was actually real. Now I am stuck at 40fps max :/

        @[deleted] can you look into it?

        GPU is up to date, K-Lite Codecs kinda messed up my PC for some reason so I couldnt listen to any video or audio files anymore.
        But if I may ask the question, how come that my lower perfomance Setup with the SLR App was working better then my better Setup on Windows 10 now? Even when watching the stuff not local?

        Seriousguy98 Task Manager says that my GPU is going up onto 90% for 3D rendering when playing a video.

        If this is still the case, it's not using your graphics card for hardware decoding. Task manager should show 'video decode' activity on the GPU section when playing VR videos, not 3D rendering activity (or not much, definitely not 90%). The RTX 2070 shouldn't have any issues with these videos if it's using the hardware video decoding. LAV filters and using DirectPlay in DeoVR/SLRapp should work, but if task manager still shows 3D rendering instead of video decode something is configured wrong and it's probably still not using hardware decoding.

        (also there's little difference if it's playing from local files or streaming, both are video that need to be decoded.)

            Aerowen Maybe you can help me? What should my LAV filters Settings look like? What do I have to do so it renders over my GPU?

            On my LAV Configuration Settings, I use NVIDIA CUVID as Hardware Decoder

              It should be set up correctly after installation, but here is a screenshot to check. The only difference is you indeed should have set NVIDIA CUVID as the hardware decoder.

              I too have had issues with these all-in-one codec packs that just mess things up somehow. So you could try uninstalling K-Lite and install only LAVFilters from the original source here on github. The installer may ask some things about which filetypes it should run LAVfilters with but all defaults are good so you shouldn't have to change anything.

              Then check again if task manager shows 'video decode' activity on the GPU section when playing VR videos in DeoVR/SLR player.

                Aerowen So apparrently my last answer did not get published... I have installed K-Lite, LAV-Filters and the HEVC Extension. It is all running over NVIDIA CUVID now but my videos still lag when not downloaded (200k download speed) in the weird way I explained above. Also: It was perfectly fine when using the 970 on Windows 7.
                When playing local files, my normal DeoVR Player also only gets up to 40 fps... halp
                My Task Manager still does not show any signs of Video decoding, HOWEVER he is going up to about 10% for video ENcoding

                  [unknown] I currently got some improvement in my Video Quality (Like I said since my old setup, nothing changed except for Win 10 and I was running 90fps back then without a doubt on stream and not on local files). Right now I get around 60 fps with some 10-20 spikes inbetween. That would be the last thing I would have to get rid off but still no idea how...
                  I did that test anyways: It has the ID 1418

                  [unknown] Fresh Install to Windows 10. I use an HTC Vive and the laggy experience is the exact same with local files. When watching non-local files I can always tell that the download is much further in the video, so it should not be my internet.

                  I am having the same problems with on and offline files. All you suggested has already been done. I am trying all resolutions.

                  7 days later

                  It just goes up and down from 10 to 60 and back... I am frustrated... Wish I never switched to Windows 10...
                  What do I need to see in Task Manager when it plays the video? Video Decoding or Encoding!?

                  Last Update (Found a Fix!): So I was playing around with a lot of Settings now, since I installed the Advanced Settings for Steam VR.
                  What caused the issue in the end, was the Super Sampling Setting. It looks like it makes the videos turn laggy as long as the Setting is not perfectly set to 1.0 Supersampling (Which would mean no involved change from the Addon).
                  So if anyone else has the laggy experience aswell, it might be cause of Supersampling. (This problem seems to be only on the SLR App, so maybe you can find a fix for that? Dunno)
                  Anyways thanks for helping me with the codecs stuff, I can finally enjoy the App again without having to download any of the videos.
