This seems more likely to be to get developers to have cards that can handle ray tracing. My guess for gamers it will be to show them what it looks like but probably more of at 30FPS. The Crytek demo was 4K at 30FPS which most people wouldn’t call playable thing is though the lighting doesn’t become much easier at 1080p so your probably still looking at around 30FPS. So consider that it might be more of a tech demo to show people why to upgrade rather then you will be playing Metro Exodus with ray tracing on.

I do wonder if they can lighten the load from ray tracing down to a level that it's viable to use on the 10 series cards, and still something that you can see a difference on. but my guess is that it'd be better for them if it works fully as possible, but much slower, and use the appeal of higher/usable FPS to entice upgrades.

Following AMD's claims on software-based real-time ray tracing in games...
Again, why is it being called "software-based" ray tracing? It uses hardware. It uses GPU compute cores. It's like calling BF5 ray tracing "spftware-based" because BF5 is the software which causes the ray tracing to happen. Nonsense. They are both hardware-based solutions. The only difference is that one uses a dedicated cluster of compute cores ("tensor cores") and the other uses a general purpose cluster of GPU compute cores. Using a dedicated cluster benefits by not utilizing general purpose clusters which can then by used for other purposes. Both are hardware-based.

This is Nvidia playing games again. They pulled the same thing with G-Sync and FreeSync. They claim compatibility with a non-proprietary version of their tech and implement it subpar to their proprietary version (then in a self fulfilling prophesy claim the Nvidia version is better). Nvidia is getting rather shrewd in their marketing tactics this series. This is how they can now negate them being called out on proprietary features. I foresee the next example of this will be SLI vs DX12 multi-GPU performance implementation.

Well I am not going to cry if it does, I mean its not like I spent a lot of money on my GPU so theres that. If i get crappy performance with ray tracing fine then, its not a priority I have it anyhow

What AMD's claim do you refer to? The only reason their GPUs don't support DXR is because they aren't exposing the functionality in their driver. I also highly doubt that this announcement has even remotely something to do with the CryTek's demo, they made it yesterday which (oh, but look what a coincidence) was the opening day of the GDC. How do you think every RTX game/demo/benchmark run on the Titan V? I'm amazed how fast people forgot that it was the first DXR supporting card (all developer start working on it before Turing was available).

This 100% depends on the benchmarks. Right now people say enabling it will drop the frame rates down to almost unplayable levels. It’s not like a 2080 and a 1080Ti will get the same frame rates with ray tracing on. It could be that people will see what it looks like but it will be at like 30FPS vs. 60 or 70FPS.

I think people should take a moment a wonder what does NVIDA get out of it. If software Ray Tracing works well then they just killed the RTX line off. If this is hardly playable they just showed why the RTX line is worth investing in. For NVIDIA it’s better the last generation you can’t buy anymore to not do so good in the benchmarks.
On the flip side though a lot of developers will now have systems that support ray tracing and if they get 20-30fps it’s good enough for development.

1, hardware accelerated dedicated cores will be 2-3 or 4x faster than software based cuda cores doing the same work(and take less space) - and that takes those cores away from general rendering 2. dedicated cores will always be more efficient power wise as well - less circuitry -better use of space and power if i had to utilize space efficiently - id take the dedicated cores over the general cores - provided we don't start putting too many specialized circuits in - and have idle circuits depending on the load yes right now turing on older gaming platforms is a waste of circuitry - but as more and more games use DXR then turing makes better use of raw horsepower and if DXR is the future then moving to turing made sense either now or later - and you might as well start off adopting the tech early to spurn on the development cycle for games

If this was done strategically to get more devs behind the RT train, Nvidia is a genius. Xavier Zepherious 1, hardware accelerated dedicated cores will be 2-3 or 4x faster than software based cuda cores doing the same work(and take less space) - and that takes those cores away from general rendering 2. dedicated cores will always be more efficient power wise as well - less circuitry -better use of space and power if i had to utilize space efficiently - id take the dedicated cores over the general cores - provided we don't start putting too many specialized circuits in - and have idle circuits depending on the load yes right now turing on older gaming platforms is a waste of circuitry - but as more and more games use DXR then turing makes better use of raw horsepower and if DXR is the future then moving to turing made sense either now or later - and you might as well start off adopting the tech early to spurn on the development cycle for games
I hope this is the case and agree. I would think these cores are specifically designed versus a one size fits all approach core like CUDA. The same can be said with the Tensor Cores. If this isn't the case, Nvidia would have shot themselves in the foot but I'm being a hopeful RTX owner that this isn't the case because it would be the silliest thing a billion dollar company would do and risk losing major sales and reputations. I think Nvidia has gone to its 'plan B', giving some of their non-RTX GPU consumers a taste of RT because all of the toxicity in the air about it all and what its capable of with the right equipment (High end RTX GPUs) since more devs will be implementing to their titles and possibly existing titles as well. That would blow the RT doors wide open what should have been done prior.

Frankly, I ran the Shadows of the Tomb Raider benchmark with and without DLSS. With DLSS, it averages 77 fps...without it averages 63. This is with a 2080 TI. I can't imagine the 10xx series being able to run RTX with any appreciable fps. The software emulation is going to tax the card very hard. Will have to see how it effects the 20XX series as well.

LOL i find it funny. Sure you may have the RTX GPUs running RT better than the GTX 1080Ti, but you guys have not seen the big pic here .....what AMD GPU series is running the Crytek demo? and how good is running it? compare to the cards recently released, i said the lesser GPU is giving a good run for its money to those that own a card twice the price? Yeah, well, i guess AMD computation cores are more important than Tensor cores in my opinion

I think you're missing the point. This is more like driving a V10 Lambo in traffic. It looks prettier along side the Pinto but ultimately they both perform the task equally, getting you from point A to point B within the same time frame. Have fun.

that's the point they are not performing equally - where is an independent review of performance on non-rtx cards running Ray tracing - there aren't any - and if there were we would see cards doing significantly less lets see some numbers not a demo... im not taking AMD word on anything either or some single site with some grudge or not any real comparisons on RT intemsive games- like cherry picking the settings and the type of RT game(not one with the least of amount or RT work in it) lets pick the most grueling games and test it

RTX cards perform better when settings are neutral. When DXR is on this happens: https://forums.evga.com/FindPost/2935107 What's the point of paying for something that makes little to no difference??? This tech was introduced too early, it's not mature, and anyone who purchased an RTX branded VGA got rolled. Nvidia is allowing ray tracing on 10 and 16 series cards, now, no doubt with an fps penalty. Maybe the RADEON VII's extra memory bandwidth will help it with RT, who knows? No reason not to believe AMD if you believed Nvidia. The way I see it, they both have work to do, Nvidia having the lead with tensor cores and I'm glad they are pushing ray tracing into mainstream gaming. Did AMD not have RADEON Rays prior to this, though???

I would look more for cache size and L1 latency than memory bandwidth, there are a lot of paper if you are really interested. Radeon rays is for developers for backing light or previewing models/scenes, NVIDIA offer this since Fermi with Optix...

It should work but not fast, the more rays are shoot the more RTX card will show their advantage.

Stefem I would look more for cache size and L1 latency than memory bandwidth, there are a lot of paper if you are really interested.
As a matter of fact. I'd like to understand more why HBM2 is superior than even GDDR6 and whether it will benefit future implementations such as ray tracing.

Xavier Zepherious thats alright - i'll stay in my lambo and you can keep using your pinto...putt puttt ...puttt.puttt itl like putting AC in a 4cyl honda - vs AC in a cadillac the honda will stall going uphill - that caddy will be speeding
There is a Pinto around here with a blown 408 Windsor, tubbed, caged and sounds simply awesome. Crazy thing is the cage is built around a child's car seat in the back. My money is on this Pinto, not the Lambo.
