Echoing what others have said, a "gaming distro" really isn't necessary. I have used Ubuntu for years on and off. When I switched my gaming PC to Linux earlier this year I went with Kubuntu, because it's just Ubuntu and I like KDE Plasma better than Gnome. I do feel like Ubuntu is one of the easiest to find support for when you're looking online.

I've been doing this with Flashlight Tiramisu for years. Even replaced the quick settings button with one that opens that app instead of I long press it. Good that it's baking into the OS though. Mostly mentioning for anyone who doesn't want to wait.

I use Abraham Linksys, even now that I've moved on from Linksys routers (mostly too lazy to update all my IoT devices).
