I don’t know if it’s the encoder or Wayland being Wayland, but there stutters on the stream (but not the host screen) using VA-API.
Using the same host/receiver on windows (but a different encoder) there’s no issue so not sure it’s related to VRR or framerate matching as many suggest.

I did exactly this but unfortunately it didn’t address the issue I was experiencing. I read the manual you linked and the support forum for Sunshine.
I posted about it in support forums and also got helpful advice about network latency, matching res and refresh rates to host, running Wayland only session, running game scope, using Apollo, etc.It unfortunately didn’t help.
I tried it on Bazzite (where it is preconfigured) and CachyOS and got the same result on both.
It suspect it’s the encoder but I think it could be a Wayland issue. I didn’t test X11 as that didn’t really suit my purposes.
I explored this issue pretty thoroughly and spent hours trying to solve it :(
