Debian is great for gaming just takes a little work. I run Debian sid and that has its pros and cons but I do it to have super updated packages and to help report bugs. But running stable with a mix of flatpaks and backports works great as well.

Debian is great since it's just super vanilla packages from upstream for you to make it the way you want it.

I'm in a similar boat as you and my current plan is to switch to PopOS. They are Ubuntu/Debian based so you will be familiar with it, and they also are a distro that is more focused on gaming, so you will have an easier time with video card drivers.

IMO it's not that Debian isn't good for gaming. It's that it's not good for gaming IF you want to just install Debian and start gaming right away. There's going to be a bit of downloading/installing, & configuring first.

If Debian is too far back of a starting point for you then I'd either go with a gaming distro where many things will already come installed and possibly (idk for sure because I've not used any gaming distros) configured for you to where you mostly just need to sign in and download your games.

I switched from arch to Debian bookworm for my work/gaming pc, and I have no regrets. Same amount of time setting up as arch, because of the newer kernel on bookworm you don’t have many prerequisites to install. Was gaming within an hour or two. That was six months ago, and things don’t break all the time like arch, where they would fix graphics drivers, but doing so would bork the sound. I play everything from factorio to cyberpunk, no issues. Only thing I can not get running for the life of me on windows or Linux is forza motorsports.

I don’t think distro matters as much anymore with modern Linux. There are enough tutorials out there on most of them, should be easy to get setup on almost anything.

Idk how well Debian stable would work, but Debian Sid might be a bit easier to work with in terms of games with it being more on the bleeding edge.

There's also Linux Mint Debian if you want to stay in the Debian universe, but you'd get more of the ease of use of Mint.

Me personally, I'm using Fedora for gaming and I haven't really had many issues with it. If you're feeling adventurous, you could try Fedora or Nobara, which is a more gaming focused spinoff of Fedora

“not the greatest at gaming” is still perfectly fine – the main argument against Debian stable (at least for gamers) is that, since Debian’s focus is on stability, they’re not riding the bleeding edge of updates and features

Currently running debian with an amd GPU. Using the regular 6.1 kernel

With steam flatpak and bottles (for nonsteam windows games) everything is running just fine.

Fedora Silverblue and Linux Mint Debian Edition are my goto distros atm. Have not had issues with either, they've been great out of the box. Fedora Silverblue requires relearning a few things however, being very container oriented.

Mint

AMD or Nvidia?

I been running Debian with a few Backports like Pipewire, Kernel, and Flatpak it has been good so far.

I was daily driving arch for 5 years and decided to switch two months ago just like you now and running Debian 12 happily, tried fedora, set subvolumes to timeshift btrfs to work because it was not installed out of the box, and after update from 38 to 39 with official gui update tool, it broke and locked away ssd so i had to recover data, after that i installed Debian 12 and had no problems at all, machine ALWAYS ready to work and stable as fuck, heavenly experience so far actually

Debian is fine, but not that great if you wanna game, it's packages are kinda old and that matters a lot of you wanna game on linux, as the scene is rapidly evolving, even as we speak. It will work, you just might have issues with certain packages being to old and games not running as well as they should... If you want a gaming 1st distro, try nobara or something with newer packages, like EndeavorOS.

Another thing that matters a lot when it comes to gaming on linux is the desktop environment and display server. It's a big topic and I'm gonna get hated on, no matter what I recommend here, but my personal recommendation is to use the KDE Plasma desktop with the Wayland session. Again, it's a big topic and you should look up the pros and cons of using Wayland or X11 for gaming, I recommend using Wayland to avoid certain headaches with X11 and to have a generally more usable system while gaming...

I’m using Debian testing + a few packages from experimental (Mesa) and xanmod or liquorix kernel.

It’s been a great experience. Stable as expected, performant as anything else.

I've used Debian before on my gaming laptop (nvidia card), but drivers were enough of a pain that I just switched to Mint. As much as Canonical annoys me, drivers have been much more plug-and-play for me on Ubuntu downstreams than on raw Debian.

Debian Sid should be fine. I wouldn't go with Stable − too old.

Personally, I'd go with the Flathub version of Steam and not pollute my main system with 32bit libraries Steam required for backwards compatibility. With the 32bit dependencies as Flatpak Runtimes, the main system stays clean.
