I just got it up and running, so here’s first impressions and feedback. Installation was simple, just about 5/10 mins in total. UI looks great, super clean. Game installation process seems great but I only had time to try one small game (celeste). For some reason I had 4 Celeste shortcuts show up in Steam. Deleted 3. None had artwork (don’t know if that’s a feature yet), but I just used SteamGridDB plugin. On launching it took too long so I rebooted. Same thing again, but after changing to Proton Experimental, it booted after a minute. Second boot was very fast.

Basically, it seems great even now. I will test in more but in current state, seems at least useable and useful to me. I never touched my Epic games, but will do now.

Not really a workaround, but better alternatives exist. Greenlight and Xbplay will give better image quality and latency than edge. And Xbplay lets you add shortcuts to steam.
