just a FYI
the raytraced reflection demo they showed at launch (the stormtroopers) was running on a $60000 Nvidia DGX workstation with 4 Tesla v100 gpus and a XEON processor (a single telsa v100 costs about 10 grand, and a top of the line XEON is about the same)
you won't be seeing anything like that in games for a LONG time. (when it comes down to it that was a pretty simple scene for a ray trace engine to produce... all nice clean surfaces with hard edges, in the interior of a building with "man made" lighting) even their 60 grand supercomputer couldn't render Forza with ray traced shadows and reflections in real time.

their launch was sold on a lie. (most people would rightly assume that when a company releases a new card that the demos they show are actually running on that card)
"NVIDIA did manage to run it on a single Quadro RTX 6000 graphics card. This card will cost $6300 when it’s released later this year"
OH well that makes it ok i guess (sarcasm btw), they have pulled a bait and switch of epic proportions. (and i bet many pre order people were taken in by the lie)
I've been into 3d modelling since Lightwave on the Amiga so I instantly smelled something fishy and did a little digging. (turns out i was right to be sceptical)
the 2 games that i have seen demoed (shadow of tomb raider and Metro) had NO ray traced reflections (both of these games are using a mixture of ray traced shadows and normal rasterized graphics.
the improvement in graphical fidelity is minimal from what I've seen.
They are not ray tracing the full scene, ONLY the shadows are ray traced (shadows are the easiest and quickest thing for a ray trace engine to render) also of note that this demo was of a character slowly walking around an enclosed space, once the bullets are flying and you're running about like a headless chicken with explosions going off how is it gonna fair? and the metro demo was a scripted slow camera pan, again through an enclosed building.
this tech will be another hairworks or physX that won't appear for years in any games made by devs who are not on Nvidias payroll
people have got the wrong end of the stick, a lot of people I've talked to seem to think this will be a magic bullet to photo realism.
there is FAR more to making a scene photo realistic than having ray traced shadows.
it's gonna be another dead on arrival gimmick from Nvidia. (hairworks is still in limbo 4 or so years down the line)
and most people who had a hairworks compatible card at the time turned it on for 5 seconds in the witcher 3 then turned it straight back off again because it completely tanked your frames (And that was pretty much the last we heard of it)
here's an image to show the difference between ray traced and faked shadows (not rendered on an RTX card btw it's just an example of the different techniques)

the improvement is minimal and you'll be hard pushed to tell the difference once the scene is in motion, devs have been able to fake convincing enough shadows for decades. (the difference in render times would have been significant tho with the ray traced probably taking 10 times as long to render) and even the ray traced render is CLEARLY computer generated and a long way from photo realism
almost double the price for slightly more accurate shadows? um no thanks Nvidia.
TLDR: Yeah they are having a laugh, it's all just corporate buzzword nonsense and if you are in the market for a new GPU get a 1080Ti (it's still gonna be good for years)
