I’ve used PopOS as a daily driver on my gaming rig for about a year now. No real complaints and it was definitely great when I had an nvidia card.
(Though I am looking to switch to Arch soon, since I want to really avoid background processes that I ultimately don’t need, and since I switched to AMD and their drivers are in the kernel, I don’t need the nvidia help anymore.)
I remember when it came out and thinking “really? What can you even play?” And then when the Steam boxes seemed to flop, I figured that was the end of that.
But now I’m hugely happy they stuck to it. SteamDeck is a great success and I’ve been daily driving linux for gaming for about a year now. Tremendous boon to the community.
