It still has a long way to go. I only noticed raytracing in two games so far, Metro Exodus Enhanced and Control. It looks really nice in those games and I don't wanna miss it. In BF5, Cyberpunk and Tomb Raider however, I can't say if I'm playing with raytracing enabled or not.
Devs need to put some more work into it. If it's well done, it makes a hell of a difference and really looks like next-gen. But right now that's the exception, not the rule. You won't miss anything if you just wait a few years before investing into raytracing tbqh.
