Today, I switched the last of my Windows machines to Linux: my gaming PC. I’ve been using Linux on servers for many years but was a bit apprehensive for gaming.
Turns out it just… works. Just installed steam and turned proton on, have zero performance or other issues. I’m using Ubuntu 25.04 for the 6.14 kernels NT emulation performance tweaks. Aside from there not being a catalyst driver for it and so I can’t undervolt my card everything is great.
You made the right call, for your situation.
They’re just letting you know that you will want to apply each annual upgrade when they come out, to ensure your system stays secure.
This may contrast with any Ubuntu-running friends you may have, who may not be applying updates annually.
Once you’ve upgraded to 28 (in ~ 2028) you can safely skip the next four years of updates, if you feel like it, because 28 will (probably) be the next Long Term Support (LTS) release.
