getting low fps and/or black/frozen screen when streaming cemu emulator to steam link

[richter.ton]

Hey there,

I spent the night trying to get my cemu emulator to run on my TV via steam link.
I am getting this log, showing me, that the client is targeting low fps and/or resolution sometimes...i think this is the reason for the bad performance, but I really don't know what to change anymore!
Any other game is streaming nicely in fullscreen and window mode!

Thank you !
