Way more than I thought it would be for some time. This bodes well for the technology. Hopefully it continues to be popular and gets more traction instead of dying off after the initial support from these 21 games

I don't see it dying any time soon, I just hope it doesn't run poorly on AMD hardware.
Sounds like Hairworks 2.0 to me so far, but with actual graphics improvements.
they basically throw in a few features.
the problem i have is that no title seems to support all of it..... shadows, reflections and GI etc.
maybe i am wrong and these titles support all of that.
if not.... i wonder if performance is still not high enough.
RT sure helps the artists.
i do 3d archviz freelancing beside my day job.
and thank god i don´t have to care about texture baking, light baking etc.
raytracing takes care of that. so i can spend my time on more important (satisfying) things.
baking is not exactly my favorite thing to do (just like UV mapping it´s a mostly unloved part of the 3D work).
that said it will be some years until game engines will be purely raytracing based.

There's a few already-released games there. That means that without RT enabled the game should look as it was and run as it did, right?
right.
and with RT enabled it will run like crap on nvidia GTX cards and will probably unplayable on AMD cards... so you will want a RTX card.
i guess nvidia will even waste 30% of the RT performance just to make AMD cards look even WORSE then they would. it will slow down nvidia cards too but much more will it slow down AMD cards.
they have done that before with hairworks, gameworks, tesselation.
some of these features produced so much unnecessary overhead in some nvidia sponsored titles, that they slowed down nvidia cards but made AMD look terrible compared.
when you have a dedicated RT coprocessor that offers "10 gigapixel" of RT calculations a second (just to have a number) it doesn´t matter if you use 5 gigapixel/s for the calculation even when only 2 gigapixel/s would be sufficient.
but when you have a GPU that can barely deliver 1-2 gigapixel/s... it does matter.
in some nvidia sponsored titles we have seen stuff calculated that was not visible in the scene.... but nvidia could widen the performance gap to AMD that way.

Oh.My.God. I just saw that Battlefield V ray tracing demo. So cringeworthy.
That's what Nvidia is hyping up so much? A freakin' reflection and lighting tech? This is like Nvidia's push for tessellation all over again. Performance killer that doesn't really look all that different than what already exists. For the love of god don't fall for this crap again, folks.

The whole point of RayTracing is because of lighting... Reflections are a great example of that.
Also realize they probably only had a month to get a working demo together.

Yes. They are just jumping on the bandwagon, will no doubt bodge something in after the fact then push it as a RT title.
TBH having seen that demo I will not be buying BF5. At all. Not if they really want to make the regular one look so crap.
Mind you I didn't buy BF1 either.

TBH the reveal of so many titles so quickly shows that Real-time Ray tracing won't just be the fart in the wind that some people expect.
Remember that RTX is Nvidia's software that deals with Ray Tracing for DirectX 12 (via DXR) and Vulkan. There is no reason why AMD couldn't make their own acceleration technology, Nvidia is just ahead of the curve in this regard.
When it comes to "why are they making the games look crap without RTX comments", it must be remembered how normal reflections work in most modern gaming titles. The "screen space reflections" used in most modern games require data that is in the "screen space", if it isn't in the screen space it cannot be used for a reflection. That is why BFV's reflections change so much.

Quantity does not = quality dude. Most of them are getting post release patches, and we all know how that usually works out.
When you have solutions that are not widely compatible with every tech every one loses out. It's been the same since day one, pretty much.
Ray Tracing is amazing and I've always loved it, but not for £1150. Certainly not.
My biggest criticism of VR (as you well know from my posts) was that it is too expensive for every one to afford and thus jump on the bandwagon. When you restrict something to a select few the cash in bothering to make decent stuff for it does not equal or greater the cash you make from it. And thus it's a catch 22, until that product fades away.
Gsync and freesync? did not stop you running a game nor making it look inferior (well, until Gameworks). But this? yeah, not touching it with a 60ft pole.
£1150. And we have not even seen exactly what the test system was running those games.
I just can't get my head around it. £1150.
more hardware than software.
i don´t think anyone thinks that game developers purposely make titles look worse without RTX.
the reflections will look like they always did without RT.
it´s just that they will now hype these RTX features without end.
remember how nvidia hyped hairworks and in the majority of titles it barely made a difference.
RT sure has great potential. after 3 generations of RTX GPU´s it may be a must have feature.
right now it seems like an easy way for nvidia to say to the gullible "look you must have that"....
early adopters always pay an extra. often it´s not worth it.
nvidia needs a HUGE title that shows the full potential of RT.
something like crysis on steroids.
the reflections in BF V are sure nice. but not enough for me to even think about buying a RTX for it.

Quite comical reading many of these complaints. Its new tech, what do you expect?
I was in uproar initially, but now I think about it, RT can be the next step into amazing immersion. This is a new direction we are moving in now, so this deserves some credit when it becomes fully utilised.
Can guarantee people will still pay for this like those who paid for a titan then used it for...gaming.
My only issue is the price is a tad higher than i like. had it been £1000 for the card I would say its justifiable. I'm seeing too much hate towards Nvidia in this thread to be honest. They own the market, they can charge what they want.
Personally I would be tempted to purchase one. But I won't be an early adopter anymore. I will wait for better derivatives of the architecture.
This is the first time a new GPU architecture has brought something new that's a visible improvement in a long time now. And the first time I've actually wanted one.
