And if you change desktop fps to 60 (without restarting PC), 3D still works?

This does not fix the issue.

Update in general: version 20H2 still has the same issue with 3D playback.
No traction yet on a fix.

Thank you for the update. This is sad, what once was a great 3D playback machine is now dead in the water.

It's not over, yet.
Finally had some time to play around with Win10 20H2 and 3D MKV and figured out how to make it work:

* Change compatibility settings on your player executable (e.g. mpc-be.exe) via right-click->Properties->Compatibility->Disable fullscreen optimizations (this gets rid of Win10 forcing a borderless window in fullscreen)
* Set madVR rendering->general settings->enable automatic fullscreen exclusive mode
* Set madVR devices->display modes->hack Direct3D to make 24.000Hz and 60.000Hz workNotice that the display rate will be the proper 23Hz to match the source rate, but the composition rate will be 60Hz.
Apparently this is a long standing issue with madVR and Windows (except for Windows v8) along with GPU drivers not playing nice with desktop composition.
I've seen similar complaints with the HDR toggle and recent changes to nVidia drivers.
I'm not used to using FSE, but have mapped all the necessary key shortcuts to my Harmony remote to solve the limitations.
Convenient ones to keep in mind: cycle through audio track and subtitle track (can't use mouse/menu without blanking screen).

Let me know if this works for you too.

Henkeli- this worked great.
Many thanks indeed.

Oh my I tried this and it has worked so thank you very much.

JimH - Can you please move this thread back to its original location or somewhere else as it is not a hardware issue!
