Well, let's see some games use AMD's ray tracing tech. It can't be any worse than nVidia's.
"Fallback layer is just an emulation layer provided by MS, which is capable of running on any "D3D12" compatible GPU." So AMD's DX12 cards can use ray tracing. hmmmm. What I'm waiting for is not light, or water, ray traced, see that Star Wars demo up there, to me that would be a turning point for games. Fully ray traced and 60FPS+. My guess 5-10 yrs away.

Make that 15-20.

Bladesfist25d ago (Edited 25d ago )

It will be and is much much worse, you need a lot of additional compute performance to match the power of the specialised hardware and the die size of these RTX GPUs is already massive. The result will be a very very expensive piece of silicon to reach the same performance as the specialised hardware.

Here is a DXR benchmark of the flagship AMD GPU vs the flagship Nvidia GPU.
Radeon VII: 10 fps
RTX 2080 Ti: 324 fps

`Fully ray traced and 60FPS+`

Good luck with that

DaDrunkenJester25d ago

Yeah, we are going to need a full generation before we see games with full ray tracing. As for now I'm loving what Metro Exodus has done with the RT Global Illumination, it makes the game gorgeous and I can run that 60fps on ultra settings on my RTX 2070 and i7-9700k.

But then if you start throwing in reflections and the whole 9 yards... it would melt PC's haha

starchild25d ago (Edited 25d ago )

I have the same card and the game does indeed look gorgeous with the ray traced global illumination. Some of the best visuals I've ever seen in a game.

If all we can get for now are games with ray traced global illumination at playable framerates I'll be perfectly satisfied. It makes a huge difference.

Over time more and more types of light interactions will be rendered with ray tracing. This is just the beginning.

I_am_Batman25d ago

The Star Wars demo is utilising a rasterization-raytracing hybrid rendering approach and is therefore not fully ray-traced. This is pretty much what we'll be seeing in terms of raytracing for the next decade to say the least. Even the ray-traced elements of the rendering pipeline have very low samples per pixel right now and are relying on denoising to produce an acceptable image.

We've seen a fully raster-free, path-tracing mod to the Quake 2 engine working on RTX cards but even though it's a 20 year old game they had to implement a lot of tricks, like culling of far away, or occluded light sources that aren't rendered inside the screen-space to make it make it run at 1080p/60fps.

Why on earth can't these companies create a standard to everyone can use them?

porkChop25d ago (Edited 25d ago )

There is a standard. Microsoft's DirectX Raytracing (DXR) is the standard and is usable by both AMD and Nvidia. Nvidia's RTX can still be used through DXR.

spwittbold25d ago

It's a marketing gimmick. They do the same shit with TVs. Right now a lot of companies advertise "120hz," tv for dirt cheap when what they are advertising is some dubious marketing scheme like "True Motion Refresh 120hz Tech," which is a layered technology that doesn't actually produce 120hz, but does help images appear to be smoother and reduce some of the transient motion blur.

OpenGL25d ago

That's actually not accurate. The panels are 120Hz, they can only accept 60Hz. (even this is changing though, many tvs already will do 1080p at 120Hz) This is still an advantage though as 24Hz divides evenly into 120Hz, making Blu-rays look better as there is no need to utilize 3:2 pull down, each of the 24 frames can simply be displayed 5x. A 60Hz signal also works fine as interpolation can be disabled so each frame is just displayed 2x. 120Hz has real benefits over 60Hz and it has nothing to do with the disgusting motion enhancing modes on most older tvs.

badz14925d ago

nVidia and standards don't go hand-in-hand. they feel the need to have something they can call their own much like exclusives such as hairworks and this RTX core or whatever to justify overpricing their GPUs

Weeblordbad25d ago

Guess you forgot about Freesync, and hairworks works with AMD GPU just like TressFX worked with Nvidia GPU they simply suffer performance wise when you aren't using the brand appropriate GPU.

The Nvidia cards justify their prices by AMD being unable to even compete. The Radeon VII barely touched the 2080 for the same price while generating more heat and using more power. But you know, it's just that greedy Nvidia, I remember when they ran a charity and not a business too.

starchild25d ago

Not all of the stuff they research and develop is proprietary. And what's wrong with having things that differentiate your product from competing products anyway? You're a Sony fanboy and Sony has a long history of creating proprietary standards, as well as limiting games to their platforms in an effort to make them more attractive. Hating on Nvidia for doing a bit of the same thing seems very hypocritical.

oneconsoleonly25d ago (Edited 25d ago )

I am not a PC gamer so I care less about it but Nvidia is ahead of AMD

dolfa25d ago

U can't really call this ray tracing, real ray tracing is entire different thing. This is like some extra shader.

Bladesfist25d ago (Edited 25d ago )

No you can call this ray tracing as that is exactly what it is, it's just much slower when done via compute.

dolfa25d ago

If you want to see real ray tracing, try render some scene in blender by ray tracing to understand what it is. Current raytracing is just applied to few objects in the scene which is why i call it bullshit.

Bladesfist25d ago

@dolfa Yes games currently use a mix of ray tracing and rasterization to generate an image but the article is clearly talking about the ray tracing side of that equation.

LightofDarkness25d ago

You're half right, this isn't a full path tracing rendering solution in practically any game. The only one I have seen using RTX that is completely path traced (that uses the Tensor cores to de-noise) is Q2VKPT, a completely path traced engine for Quake 2. And a 2080 is still only averaging around 70FPS at 1080p.

Metro uses ray traced global illumination, which is pretty amazing in its own right, but isn't fully ray traced. It's not just a shader effect, though. The whole scene is being lit using ray tracing (shadows, ambient occlusion, indirect lighting and bounces, GI essentially), but reflections and other aspects are not being taken into consideration. It has a very dramatic impact on the game.

dolfa25d ago

But still decades behind full path ray tracing...To me it just feels like Nvidia is pulling marketing word on the less capable customers. This reminds me of Physix - another marketing.

LightofDarkness25d ago

True, but the important thing is getting developers to start working with it now as a concept and to alleviate some of the immense pressure that comes from having to use teams of artists to light your scenes. With RT GI, you can just set a light source and the much of the work taken care of. It results in more accurate lighting and time/cost savings for developers.

Weeblordbad24d ago


Oh bloody stop, it's been pointed out that it's not a shader. Own your mistakes, instead of arguing about semantics.
