Describe the Bug

When hosting a stream using an M1 Mac through Sunshine, I've noticed sub-optimal streaming quality despite setting Moonlight to 4k and using ethernet. When compared side-by-side with Parsec's output, Sunshine's stream lacks the sharpness compared to Parsec. Below I have attached a comparison with Parsec on the top and Sunshine/Moonlight on the bottom. Observe difference of clarity in text on the date and time.

Expected Behavior

Streaming through Sunshine should a sharp 1080p image especially when there is no motion on the screen, Moonlight is set to 1080p and ethernet is being used.

Additional Context

I have tried numerous different adjustments to the config settings but the issue persists. It also does not appear that HEVC is functioning with Sunshine so perhaps that could be a potential cause?

@FlyGuyGo i had this issue, but with a slightly different setup (windows host streaming to a m1 mac client, with the rendered video on the client being slightly blurry) — are your resolutions matching exactly between the host and client? making sure both were the same fixed the blurriness for me

To add on to this, if its a retina display the screen size is 2x the resolution listed in display settings
