Description

Title.

A lot of users are already setting frame limiter / disabling V-Sync in Nvidia Control Panel to reduce stutter with Sunshine.

However it would require to switch back and forth between:

  • Default config (no frame limiter, vsync set to passive)
  • Sunshine config (fps limit to 60, vsync forced off)

This PR aims to make this automatic.

Screenshot

Will provide later

This one is fine, but I'm not sure why the one above is missing the conditional for the windows platform... or if any of them are even needed as the entire nvenc encoder is Windows only.

I suppose you can get this from #2894 after it's merged.

I managed to try this and it worked as expected: it changed the settings for vsync and fps limit

I'd need a bit more info on those things:

  • What would be the best place to enable the temporary settings? (should be when the stream starts, but where in the code would be the best?)
  • What would be the best place to reset the original settings?
  • It's already possible to get the display refresh rate, how to use that in my PR to replace the hardcoded "60"?

Still jittery after all these years when Vsync on, Client and Server set to same refresh rate.
