Valve has been pushing for newer technology in their video games instead of reproaching previous success, a quality over quantity which is different from what made the Steam store so successful. For a company that talked so much about controllers I am surprised they are not selling different sized variety packs. Supporting RTX is not something I see as feasibly reasonable, game systems typically max out around 60 frames per seconds in most games, I think Portal should be running at over a hundred. Most of what video games offer is an enhancement to the imagination, ray tracing does not hinder that, being able to see light react from the environment is more of an authentic simulation. What ray tracing hinders though is projected audience, price point, type of software that powers the game and the hardware it supports is based around making a visual experience that is not related to the human interaction, seriously limiting the audience.
