    Assuming that your computer's graphics chip is based on a well known brand such as Intel, Nvidia, AMD Radeon, etc then simply updating the video driver should update OpenGL support too.

    MartyG I'm back online and happy to proceed troubleshooting...

    Just recap where I am: I have latest version of Intel UHD 630 Graphics drivers on my machine: 27.20.100.9466

    I uninstalled camera drivers, so now I'm on native windows drivers: 10.0.19041.964 from 6/21/2006 by Microsoft for both Depth and RGB

    Welcome back, and thanks very much for the configuration details.  Can you confirm please if you are still experiencing lag with those drivers?

    btw, I found this tool: https://software.intel.com/content/www/us/en/develop/documentation/gpa-getting-started/top.html 

    let me know if it can be of any help.

    Next, please check if disabling Global Time Enabled in the Controls section of the Stereo Module options has any impact.

    In regard to the GPA tool, I cannot see any harm in using it, though I have not used it myself and so cannot offer advice on that particular subject.

    ok, before I go into the 'Global Time Enabled', I just noticed that with the current driver version I get "USB SCP Overflow" error in the Viewer:

     

     

    I will try now updating camera drivers.

    removing "Global Time Enabled"  did not help.

    We have gone through almost all the possibilities that we can test for in the RealSense Viewer, unfortunately.

    Could you go into 3D point cloud mode with the 3D option in the top corner please, and then enable depth first and RGB second to create a textured point cloud.  Then wave your arm around to test whether lag occurs in that depth-color mode.

    yes, the lags still occur in textured point cloud mode.

    What are my next steps? Replace the camera?

    just as a side comment: I just tried L515 camera on the same machine - it has no lags. When I open rs-capture, the frame rate looks still variable, but there's no evident lags.

    It does not seem like an obvious candidate for replacement because aside from the lag when using depth and color together, the camera is functioning normally.

    well, depth and color together is what these camera are intended to be used for.

    Besides that, just using depth produces the lags too.

    so this camera is functioning normally ONLY in RGB-only mode.

    It evidently does not do what's it intended for.

    How should I proceed with replacement?
