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.
A lot has changed since 2015 thanks to Proton. However, it’s not a magic pill. Some tinkering might be required, with how much and how often depends on what you play. So just give it a try and see it for yourself, dual boot is a viable option. Pick some user-friendly distro that handles Windows detection and offers easy video drivers installation. Are you sure that Debian is that distro given your struggles with Arch Linux? I’m not that familiar with it myself, I thought that Debian comes in a relatively raw state.
Thank you. The issue with Arch Linux was more about the performance and some games at the time just not working, which looking at ProtonDB shows they work fine now. I really enjoyed my time with Arch, all the customization and manually installing applications made it feel more personal and really “mine”. I will probably give a few distros a try before really settling in.
