I had to update to the beta branche of Steam, because when starting the Steam Link I got a pop up about installing audio drivers, but the window was unresponsive and switching to the beta branch fixed that issue. (found in this post)

So now I got it working, but I get like 10 FPS, to fix this I’ve already tried:

• Rebooting macOS and iPadOS
• Making sure all software is up to date (macOS, iPadOS, Steam, Steam Link)
• I'm going to try to have my laptop wired via a ethernet cable to see if that fixes the issue, but that isn't really a real solution at the moment

I’m on a 5GHz network, with the Mac, iPad and access point all in the same room and with a direct line of sight to each other. I’ve also tried the build in macOS SideCar feature, but this keeps coming up with “Lost Connection” every 10 seconds. It seem something is causing interference on my network, but I can't figure out what or what setting to change where.

As a side note, I just come from a year long game streaming service on which I’ve played a lot of games with a DualShock 4 controller connected to my iPad. When the service was working as it should I could stream games at 40mb/s with a decent resolution and a steady 60FPS and this was over the internet, so I would figure that streaming my Mac over the local network, would be no issue.

Below all the settings I could think of sharing.
