I've been out of the loop for 18 months or so. Has RT taken off or is still just a few titles?

I would say that it has taken off but it's not in a lot of games yet. The thing I see is we are two years in and people are talking about the future when we have fully ray traced games. Nobody is really talking about 10 years down the line how ray tracing will have been a fad.
 
The 3080 and 3070 will put the level of ray tracing into the hands of gamers who didn't really get great ray tracing in the past because of the high entry price in the last generation. If we see a 3060 with ray tracing I really can't see it not taking off in a big way. I do expect that we will see weak ray tracing from the new consoles but I am kind of figuring it's one of the things that a PRO model down the line will increase as the bonus. I can't see this generation of consoles really getting 8K and while they could go with 120FPS it seems more likely to me that they would go with ray tracing and image quality improvements also.
 
What is clear is this is not technology that will fade away but instead something that will be used. Movies have been using it since Cars came out in 2006.

Ok, then it's an easy decision to just move my 1080sc over when I build.  My gaming is 1440p at most anyway.
 
Thanks

No

In a word: No.
 
...Though when it does become standard, imagine how much cheaper the hardware pushing it will be...
