I use tumbleweed, but I had a strange issue with the flatpak version of heroic launcher. I ran a benchmark of cyberpunk 2077 with the flatpak heroic, and was averaging 100 fps. I had nixos installed on a separate hard drive and that benchmark was 160 fps. I thought there was an issue with opensuse, but I installed the flatpak version of heroic on nixos and also got 100 fps. So I installed the regular version on tumbleweed and have 160 fps. I would keep that in mind when looking at programs to launch games, whether it's wine, bottles, heroic, lutris, etc

I second Nobara, but IMO get the KDE edition of it if you're used to Windows. You'll feel much more at home.

Go with nobara.

There is no such thing as a "gaming distro" -- all GNU/Linux distros are equally good for gaming and any other task.

I have EndeavourOS, but with the nature of Bleeding Edge packages, things can break, so setup automatic snapshots with btrfs (you want this for your data anyways).

Bleeding Edge packages have the advantage of you getting the latest features, patches and improvements, which is required for some gaming cases.

I think PopOS is the best option if u have Nvidia graphics card

Anyone that has video drivers and flatpak should work in your case. If you dislike Ubuntu and don't like the direction, usually poops and mint are the ones recommended.

Not much a of a definitive answer here imo. There's a lot of distros that fit this criteria, but I would definitely stay away from Debian due to the age of the packages. As said, you don't have to go with a rolling distro but at least look for those who keep at least their gaming related packages fairly updated.

The tough part about Arch & similar rolling distros is that they can and will break when you update something, and then you have to know how to fix it. I used Manjaro & EndeavourOS for quite a while. Manjaro was actually stable for me, but when I wanted to reinstall after a couple years to switch to btrfs I thought I try EndeavourOS, due to the criticism towards Manjaro. Unfortunately it didn't even took a year for it to break and now I'm on Nobara, which is okay but also has many issues that annoy me. OpenSUSE Tumbleweed is another often mentioned one, which is rolling but with a delay too, but when I tried it out (before installing Nobara) it was extremely hard to install as the installer was buggy and when it finally was installed it was extremely broken to the point where I couldn't even change my resolution properly.

I use Debian with steam installed via flatpak

Debian with KDE Plasma desktop, it's unbeatable.

Fedora. Cutting edge but works out of box. Very little change in use compared to Ubuntu.

Debian is good but very stable so no guarantee for some package updates which is useful for gaming and maybe proton.

On a related note, this is pretty useful: https://davidotek.github.io/protonup-qt/

Garuda is amazing
