Gears 5 Dev reveals "dedicated ray tracing cores" on Project Scarlett

I think a big part of the reason there's less of a difference in noticeable graphical fidelity now is because traditional raster graphics have kind of hit a wall and not really had much in the way of meaningful improvements for over half a decade. It's kinda the same reason why the resultant fidelity jump between each generation gets smaller and less noticeable at each one even with larger and larger absolute power increases. So many games nowadays look great at minimum settings and just slightly better at ultra because of this.

but it does seem a very strange coincidence that stuff like Crossfire and SLi support seemed to fall off a cliff when the Xbone and PS4 came out. Why? because they are X86, so they had to do 0 to get it running on PC, compared to before where they had to do the work.

I think the drop in popularity in mGPU use that led to the drop in focus was a combination of the fact that truly large die GPUs had started to exist with Kepler(Titan) and GCN(Huwaii) so mGPU's "sensible price range" increased significantly beyond what most people spend on PCs(Combined with the removal of SLI headers on NVidia's mid end down cards) as well as all the research around 2012 on into frame timings and the issues of frame consistency and latency inherent to AFR setups that effectively killed its popularity for mid/low end cards as this is where those issues were exasperated, both these came before the current gen console launch and were already seen back then as the nail in the coffin for a fading technology(Though indeed there was more optimism regarding the viability of some alternatives to AFR for mGPU use back then, but these all seemed to fall short or require very specific games in practice).

RTX is one tech available on a small amount of cards supplied by one manu. Once Intel enter the market RT will become even more of a hassle to make games for. And as I said, the last PC exclusive (because Control isn't even an exclusive even though it support RT) was Crysis and look how long ago that was.

I have to disagree with this one, when Intel and AMD bring gaming orientated raytracing support to GPUs it will be through the DXR API that they & NVidia developed exactly for this purpose and that all current raytracing games available use, Microsoft took extreme care with DXR to make it completely hardware agnostic, to the degree that you can run the API via CPU right now if you wanted, although you'd get a very slow slideshow in all but basic few polygon demos. There will need to be some new code paths without a doubt but this would be a fraction of the work of the full implementation and the similarities between Turing and RDNA now are quite various, as well as the overall approach to accelerating raytracing, and given the engineers leading Intel's GPU development it's unlikely their arch will be a world apart either, especially as it would hinder uptake so significantly with modern APIs fidelity.

Won't AMD use vulkan for RT? Then again that should run on Nvidia right?

Sorry for short reply, now back on phone.

AMD were key to the development of DXR(An extension for DX12), just as NVidia and Intel were, just as all GPU vendors fundamentally dictate the way any graphics API will go as it's their hardware it has to work on, we know the Xbox Next will use DXR for its raytracing, and so we know AMD GPUs will have DXR support(And they've already had testing functionality in the RVII's drivers in the past). Nothing stopping from Khronos adding similar extensions to Vulkan(And they've indicated they will), or from a developer doing raytracing via Vulkan with their own work, but that would be a lot of extra work when the industry(Hardware vendors, game engine developers and game developers alike, as well as MS ofc) has mostly already thrown their weight behind DXR.

Where's 3Dvision? And Physx? And etc? They're gone because they didn't catch on. (As money spinners and you can add Gsync to that also)

As for dumb? I'd say I'm anything but. That's why I'm back on consoles. Because that's where the real progress has been happening. Progress I find far more exciting than gimmicks.

You missed my point entirely.


NVIDIA KNOWS.



They know that their gimmicks won't last. They just don't care. And they will keep doing the same thing because it works every time. Even if it doesn't last, people still end up buying their overpriced gimmicks.

While some games do this, not all do and the Xbox One X can run 4K fine.

This is hasn't been true for some time since the rise of TAA and how effective it is at not only edge AA but shading AA to hide fireflies from PBR for such little cost.
