I actually had to backpedal on my gaming PC from Kubuntu recently, I'm sad to say. The support for the RTX 5080 is just too rough. Every game install was chased by an hour of debugging with Claude to figure out which version of proton to use, which launch arguments to use, which between-system-and-gpu shim profile to use.

I grant: The process is much more enjoyable than doing similar things on Windows. Kubuntu treats you like an adult and will tell you what's going on, and being able to copy the sometimes esoteric nonsense in those logs into Claude and get actionable information while not remotely understanding the underlying tech is fan-bloody-tastic.

That said it was death by a thousand cuts. Some friends I hadn't heard from in awhile asked if I wanted to get on Warhammer Space Marine 2 and luckily, I had it installed! ... and was able to play after a mere 35 minutes listening to other people have fun on the call, while I was trying to figure out why the game would only launch to a black screen.

So yeah, I wussed out and went back to Windows. I'll probably try again in a few months, and hope the GPU support is better. But that's also explicitly riding on nvidia to do, and they're busy selling shovels to the AI gold-rushers.
