The other elephant in the room is the consoles, and even if they're capable of RT they also have to consider the performance capabilities versus visual payoff. As I see it the PC versions of games like Control from studios like Remedy are trailblazers, it's an early implementation (geforce 20 released in 2018, Control was 2019) as the ultra option to shakedown their implementation and start iteration early so future games will benefit, however the baseline is non-RT.
