Experience: I have a bit of experience with Linux. I started around 2008, distro-hopped weekly, decided on Debian until around 2011, when I switched to Windows as I started getting interested in gaming. Tried switching back around 2015, this time using Arch Linux for about a month, but had some bad experiences with gaming and switched back to Windows. I have had a Debian and Arch VM in Virtual Box since then for testing different applications and a more coherent environment to work with servers.
Understanding: Which brings me to now, I am really interested in using Linux for gaming, I know there is Proton from Valve and that they have been really pushing Linux gaming forward with it.
Thoughts: I have been contemplating dual booting by installing Debian to an SSD and simply using the UEFI boot menu to choose instead of having to install to the EFI of Windows.
I guess, I should just do it, as it won't affect my Windows installation, and I could test different games and if all works well, move over. This would also allow me to try different distributions, though my heart is for Debian, I even like Debian Unstable.
Note: I am sorry for the wall of text, I am just kind of anxious I guess.
As a non-technical user, I think if you have a modicum of technical knowledge it's easy to switch to Linux. But it still takes time and patience. I'm using Linux now on all of my devices (if you count Android as Linux). There is still a lot of idiosyncracy to the ecosystem but overall it's usable. I've found Vanilla OS to be a great experience overall. I had some troubles with Pop_OS! On my Nvidia GPU, that was because it's still using x11 and I use a 4k monitor with a 1080p monitor and needed fractional scaling. Haven't had any issues on Vanilla OS because it uses Wayland. But boy, I had a hard time figuring out what was going on and why my apps were blurry and games weren't displaying properly. Took a lot of googling and perseverance to figure it out, as I didn't know what a display server.
