The games I quoted run fine, and that's not a comprehensive list.
As for sense of humour, I posted my perspective following a run of 2 people saying RT off DLSS on, flipping it around and adding a caveat in the event someone claimed it wasn't possible. Which you did anyway.
Clearly not all RT games can run RT on, DLSS off and get acceptable (subjective) framerates. Portal RTX can run fine with it off, but it's not a good experience. Some others might be ok with that performance.
Back to the main topic, RT is 100% the future but needs the hardware to catch up (and/or more software optimisation) before it's widely accepted by the masses as worthwhile. For me I'm happy with it's progression so far, as having worked with 3DS Max users I could never have imagined back then that it would be possible to render in real time.
Also, the overhead it removes from devs is a great thing. No longer need to spend the time baking in scenes. So going back to rasterisation-only doesn't make sense when you can just dump a material on an object and know you're gonna get the correct lighting from your light sources without further effort.
