Questions about migrating to Arch from Pop! for a gaming rig

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...
