There was also a heavy emphasis on games being "cinematic" which necessitates photorealistic rendering.
AAA games have been pretty artless for a while now baring a couple exceptions.
Crysis 3 is over a decade old, still looks great and ran on hardware that wouldn't suffice for web browsing today. I haven't seen anything in games since then that justified a significant increase in system requirements.
I was unable to see any site that used webgl, which is almost all games site and many charting and graphing apps.
