I did read that yes. No need to be a dick.

Sheesh I wasn't trying to be. It just seemed like you listed exactly the game types I said I didn't play but could be a case for higher FPS scenarios. Your response just seemed odd to me is all; as if you skimmed over mine. I'll admit, I've done that from time to time...
My experience has been similar to
@ipaine 's; games that had physics that broke at high FPS. I believe Skyrim even had that issue at one point iirc. I haven't played games that broke at very low FPS, maybe I just didn't notice, but I've played ones that certainly didn't play well at very low FPS. Those situations you just couldn't get the timing on things correct (15-20 FPS in early releases of Star Citizen come to mind), but I think the game was actually still working fine engine-wise. But for the games I play, I don't consider 40-70 very low FPS, and as we've mentioned, with VRR the gameplay is very good.
But a lot of gameplay smoothness is definitely in the eye of the beholder. For example, I don't visually notice mouse lag much in games I play, but I used to see every single screen tear (it felt like) and found that very distracting and hard on the eyes. So when VRR came out I was thrilled with the result.
