It's not really, and I don't really run SteamVR that much anyway. I mainly use meta's Airlink or virtual desktop for streaming. The Steam Frame itself is also still really hit and miss, many accepted features on Windows are considered "not important" by Valve and they may get to it at some point. There's a lot of catching up going on.

For me it's not worth the trouble. My game PC is for 2 things only: Gaming and 3D design and for those I am ok with just using windows.

I'm not a big fan of Steam anyway, I'm more of a GOG user. I will just buy on Steam if I can't find something on GOG.
