I posted earlier about initial impressions and how VR streaming wasn't working on Fedora but I did finally get that working so I figured I'd post an update.

Last week I had installed some codecs that were recommended to me by a user in the other thread but that only got the "pancake" game streaming working. After installing all of the codecs for AMD here, the VR streaming started to work: https://rpmfusion.org/Howto/Multimedia?highlight=%28%5CbCategoryHowto%5Cb%29

I'm not sure what specific ones fixed it, but I switched to full ffmpeg, installed the additional codecs, and did everything in the "Hardware codecs with AMD" section. I've seen some other troubleshooting tips that say to add an ENV variable to the launcher, but I didn't have to do that.

After a reboot it worked without any problems (don't forget to pair the wifi dongle from the headset).

Non-VR game streaming is just about perfect. I didn't notice any lag when playing Hollow Knight: Silksong nor was there any stuttering. However, VR streaming still needs some work. I loaded up Half-Life: Alyx and successfully streamed to my headset, but it stuttered quite a bit and often dropped the video for a few seconds. When streaming from Windows on the same PC it worked much better but did still occasionally drop. My play area is in the same room as the PC so I doubt it's a distance thing.

You'll definitely want to use the SteamOS and SteamVR betas to try this, but it does feel like I'll be able to finally get rid of my Windows partition soon.
