Thanks for the feedback - I’ve installed Pop OS tonight and installed bnet, wow, unreal engine, rocket league and steam.
Battle.net had a few problems because of the host file, and Vulkan apparently needed some fiddling - but at apart from that, I must say everything runs smoothly.
I look forward to test a lot of things deeper - but for now it very much seems like an experience I could get used to.
Works fine in Chrome here?
