I had the exact same experience: been doing Linux since the 90s, both for fun and professionaly - the latter mainly in pure server configurations - finaly got around to moving my home PC (which is mainly for gaming) to Linux (using Pop!OS, since I have a Nvidia graphics card and it just supports it out of the box) and it just worked.

Only problem I have with it is that on startup of X I usually get a blank screen and have to switch my monitor OFF and back ON again.

Oh, and startup times are a fraction of Windows startup times (my Windows 10 work machine literally takes longer to wake up from hybernation than my home Linux PC takes to cold boot, and they have equivalent SSDs.

I think I got more hassle with Windows than I do with Linux.

I moved to Kubuntu recently. I'm overall happier, but I've had a number of pain points.

1. I bought DaVinci Resolve thinking they supported Linux. They do, just very poorly. Figuring out how to get that up and running was a faff. Davinci Resolve also doesn't support AAC audio on MP4 files on Linux, so I had to write a script to transcode the audio of media to WAV. It also doesn't play nice with window management. Overall, using resolve has been a huge pain.

2. I use Insta360s software just to stitch 360 video, getting that set up with bottles wasn't the most straightforward but it works now.

3. I still haven't figured out Fusion360, and I really don't want to spend the time learning a new software. I learned it before I'd started making an effort to only use cross-platform tools.

4. I bought the Xbox Store version of Forza Horizon 5 so I could play it on my PC and Xbox. I no longer have the Xbox, and I'd have to re-buy it on Steam if I wanted to play it.

5. My Index just isn't detected on Ubuntu. It was on Windows. I've tried a bunch of things, but it just doesn't show up, so I haven't been able to play VR. It might have a bad cable, but I'm not sure. Weird that it showed up before and doesn't in Kubuntu.

Linux is all about finding alternatives. There is an alternate workflow, but you might have to deal with inconveniences or put in effort to learn something new. It's been a lot of work. Also, I might need to dual boot windows to play VR stuff.

... I can't undervolt my card...

People usually use/recommend LACT for undervolting/overlocking on Linux

I had same experience. Linux install was less headache compared to windows since the only drivers I needed were nvidia.

It just works. Crazy how windows makes you forget that.

My only hangup is installing repacks or modding games. It for sure works, but it's a bigger headache. I use mint on my daily driver laptop otherwise.

Just in case you didn't know, odd numbered Ubuntu versions (in your case 25) are considered short term releases and won't be maintained beyond a year or two.

Unless you really need that version, you'll want to install 26 when it comes out next April (upgrade should be very seamless).

Even numbered versions are supported long term, often for several years.

Holy hell, the Ubuntu ISO is 6.3GB now. Soon it may not even fit onto a DL DVD.
