The biggest issue with 60FPS is the persistence blur on modern displays. Everything turns into a blurry mess as soon as you turn the camera or start scrolling. 120, 240, 480Hz etc. does a lot to close the gap with CRTs.
btw, something I didn't even think directly about until later regarding the PS5 Pro presentation was how much they showed really old games. Like The Last of Us 2. I would've really liked to see some new game build with PS5 Pro in mind, but yet again we seen souped up PS4 ports...
