I have a rig powerful enough to run a lot of last-gen games at 4K with high quality settings, and a lot of current-gen ones at mid to high settings and 1080p. The fucking redesigned Steam library lags, none of the animations (why does it need animations?!) are even close to smooth, and there's massive delay on every input. I've never once encountered a move toward webtech, or toward heavier and "appier" JS use in something that's already webtech, and gone "oh good, this works much better now, I'm so glad they did that."
