  • Performance getting worse and worse each update

Been a paying subscriber for almost 2 years in the last few months after each update things getting worse and worse during video playback. No problem in the menu screens or any other Steam VR game. Video playback is a mess now, with it constantly losing tracking, video data load is glitching not loading in, the video signal is blinking out entirely for seconds at a time with the screen going white.

-1080GTX video card only being utilized 25%... I lowered resolution in both the app and steam VR down to minimum with basically no video load whatsoever (20% screen percentage in Steam VR, 1440P video quality in the game) and problem still happens.
-FFS.. I have the best processor on the market today (nearly)... 16 CORE I9-9900K running at 5 GHZ. Definitely
appears to be processor related like it can't handle the various tasks anymore after whatever updated with the App. Worked perfectly with the same quality of video playback (highest settings) for a few years up until last few months when I updated Windows.

Seems to be related to Windows Real Time Malware scanning. I turn that off and everything works fine for about 10 seconds and then it seems that Windows starts its real time scanning again on its own even though it says its off. I turned on "Stop External Tampering" in windows security and that seemed to stop all the problems for a long time, but it all eventually started again. I made sure everything is connected right, SLR App is allowed through Windows Firewall.

All started after I was forced to update Windows and then after each SLR update it has gotten progressively worse to the point where Im ready to cancel my monthly subscription. Fiber Optic gigabyte internet, speed test shows 800 MBits/sec.

Also added the SLR.dll process as an exclusion in windows security. Thought it solved it.. as everything was smooth for about 20 seconds like it used to be. Then it all started up again. Glitchy headtracking, video losing signal, not loading in right etc.

Hope you can get this straightened out with windows, seems Microsoft is intent on not letting this application work.

    dishymars Video and game rendering are not comparable. It doesn't even use the same parts on your graphics card. The GPU is used for the UI, but not for the video. The codec chip does the video.
    Many video-related devices don't have a GPU.

    Can you disable Smoothing in the SteamVR settings? It's great for 3D rendered visuals but not for video playback. Which headset are you using?

    Did you add or replace any monitors recently?

    In your Task Manager, is there a COM Surrogate using a lot of resources? Idle they should be at 0% CPU usage. If there is one using a lot of resources, you can terminate it.

      You're getting high CPU usage and relatively low GPU usage? I had the same problem after a recent Windows update. I troubleshooted for hours and tried everything mentioned on this forum, but for some reason it was reinstalling the SLR app that finally worked.

      I have an I7-8700 and 1080 TI, and get about 5% CPU and almost 100% GPU while streaming. If you're getting high CPU usage I suggest you try my setup:
      - Lav Filters (not K-Lite)
      - DXVA2 (copy-back)
      - Direct Show Off
      - Reinstall SLR desktop app

      Some of your issues with headtracking sound like they might be unrelated, not sure about that. If all else fails, doing a clean install of Windows will definitely fix it.

        SuperM Yeah, High CPU usage, black artifacts, point to the CPU trying to decode h265 in real time. You need a much more powerful CPU for that, like an Epic or quad Xeon. Basically server grade and quad or octo channel mem.

        Your 1080 should be able to handle it fine depending on your monitor configuration.

          Expect re-factored Steam version during next week. That should boost performance really well as we changed core components

            Reinstalling solved it! Thanks all. At first same issues came up. But shortly after the standard Windows Warning came up asking me if I wanted to allow the program. This appears to have been the key as after accepting that, back to silky smooth. It seems that if you for some reason you disregard that warning window after first installing you are screwed no matter what, as even after going in and making firewall exceptions etc, it will not call off windows security and leave it alone.

            Thought I solved this issue but still getting extremely choppy experience. Also says 70% CPU usage and only around 30% GPU usage which leads me to think the video rendering is being done by the CPU (CPU I9-9900K, GPU is 1080GTX)

              dishymars are these h264 videos larger than 2160p? If so, use h265 and make sure the Windows HEVC codec is installed.
