I've been using Arch on an old laptop for a few years now, but I use Pop on my gaming desktop. I've wanted to switch to Arch for a long while now, but haven't had the motivation (if it ain't broke, and all that). I'm finally ready to do it, but I'm a little concerned about my gaming experience. Are there any gotchas for gaming with an i7 and a 3070 ti that I should be aware of before I make the switch? Is it pretty seamless? Can I still use a freesync monitor with the g-sync compatibility setting? Is it easy to install the Nvidia drivers and well documented on the wiki? I'm open to information about any other sticky scenarios you guys encountered getting Arch set up for use as a daily driver and gaming computer.

Edit: is there any way to backup my internal drive mappings and mounting points, or will I need to set all of that up again?

I've only ever used Gnome for Arch, but one of the things that has me motivated to switch is that KDE 6 supports HDR. Does anyone have experience with it? Is it a pretty slick and simple DE?
