Here it is: the very first-ever benchmarks of production ray tracing code, via Nvidia's RTX hardware and Microsoft's new API!

The 2080 Ti loses 44% of its frames with ray tracing on; the 2080, 52%; the 2070, 56%. I don't know what I was expecting, but in looking at the graph it seems more than reasonable to me, given that this is the equivalent of a first-gen 3d accelerator, from 1995. This real-time ray tracing is that pioneering, and unlike a Matrox Millenium, it's already usable!

Now that the dust has settled, the star in this three-product lineup is the RTX 2070; while I don't regret my 2080 purchase at all-- it's presently running Fallout 76 at native 4K, with HDR, at Ultra detail and 60 fps-- the 2070 is easily the best value for money. Especially in games which will utilize "DLSS", the 2070 will deliver phenomenal performance even in 4K.

But back to ray tracing: the first title I'm going to buy which uses it is the upcoming "Metro" release. After that, it will be the new "Mechwarrior" game.
