Depending on what games you are playing, it should be a breeze. I ditched my windows installation last march and no regrets so far. Most of the games I enjoy run OOB in Linux, but some that I played occasionally are not supported, so I just live without them.
He has a Nvidia card, I had a really bad UX with my rtx 4080 with Wayland a few weeks ago. There's a protocol that just got merged supporting explicitly sync last week that may get Nvidia better with Wayland in the upcoming months though.
Same boat here. The Travel case is indeed awesome. I ended up fully retiring the original case.
I tried it with gnome recently and had the same behavior on steam and my browser, ended up rolling back to x11. I can tell I had less issues than the last time I tried it a year ago though :)
This is what I was about to write hahaha
If the OP is looking to do things like he does in Windows, just use Windows. I've been daily driving MacOS, Linux and Windows (which I fully dropped a few weeks ago) and I have a different workflow in each one. You can't expect the same behavior/approach in a different OS (in Linux, even in different distros).
In the end, just use what works for you. If you wanna try something else, the "easier" path is to just adjust to that OS, unless you are into customizing it to whatever you are used to, what does not seem to be the interest of the OP.
But I have to say, it is a pain in the ass whenever to be judged because you like/dislike and operating system. Just live your life hahaha
