The problem with Arch is that it's philosophy includes having to set up everything correctly yourself rather than each package you install already being set up and preconfigured the way you'd expect it to be in other distros. You shouldn't need to be fiddling with system stuff at all with something user focused like Pop!OS since I believe it even handles nvidia drivers for you. I wouldn't be using arch myself if I didn't have significant amounts of free time to invest into chasing down every little problem I encountered using it in college.

Linux is in a weird spot right now where the two ends of the user spectrum seem to be handled well while the middle still has issues since they're not already experts or just need an internet browser to be completely happy.

I can’t imagine a different distro would be any different.

BZZZZZZZZZZZT I'm sorry but that answer was not correct. Next player!

Seriously try some of the other distros and you'll have a much more pleasant experience. I already recommended Tumbleweed in another reply but man, anything but Arch is gonna be an improvement for somebody trying to make the switch from Windows gaming for the first time.

Try Bazzite.

Linux at work and Linux for gaming are two very different beasts. For example, you didn't mention which drivers and DE (or WM) you're using which are the most crucial part to how games run, and both of which need to be manually configured on Arch but come pre-configured or are a couple clicks away in other distros.

A different distro like Pop is completely different. My Pop gaming computer runs better than Windows on the same computer and didn't require any fiddling at all. It even comes with the latest stable Nvidia driver right out of the box, and you can upgrade it with the click of a button.
