NVIDIA Pushes Out DirectX 12 Ultimate Developer Preview Driver 450.82

btarunr · Apr 17, 2020

NVIDIA pushed out one of its first DirectX 12 Ultimate Developer Preview drivers to its NVIDIA Developer ecosystem. The version 450.82 drivers ship with all the ingredients needed for DirectX 12 Ultimate logo certification: software for DXR 1.1 ray-tracing, Variable-rate shading (VRS, tiers 1 and 2), Mesh Shaders, and Sampler Feedback. All NVIDIA GeForce RTX 20-series and Quadro RTX graphics cards already meet DirectX 12 Ultimate requirements. "This preview driver is intended for developers testing their applications with DirectX 12 Ultimate. This driver supports DXR Tier 1.1, Sampler Feedback, and Mesh Shaders," reads the brief description of the drivers.

NVIDIA does not intend these drivers for public use, but rather members of its NVIDIA Developer Program. Use of the software comes with no warranties. The driver isn't listed in the GeForce drivers pages, not even as a beta, and on the NDP page, the download links spawn a login gate. Apparently anyone can sign up for the NVIDIA Developer Program and download these drivers. The version numbering of the preview drivers suggests that NVIDIA's R450 public release drivers will bear the DirectX 12 Ultimate logo, enabling all API features on GeForce and Quadro hardware that support them.

Arnt technically the GTX1000 series also DX12 ultimate compatible? or dont they support that VRS etc?

Nope, neither GTX 10-series, not GTX 16-series meet DX12U requirements.

Shouldn't the 1600 series be fine? The only thing missing is ray tracing.
They do have VRS:

Even the newest Radeon RX 5700 XT doesn't support DX12U. What a fall and joke from AMD! That brings the hardware for most gaming systems worldwide with the consoles and gaming graphics cards.

How when it doesn't support hardware DXR 1.1 ray-tracing?

You must support ALL of the features.

Not entirely sure what the first part is about, lets not forget that by the time DX12U will actually become a prominent thing we will be atleast 2 generations of gpu's further.

On the second part, did Nvidia now allow for Ray Tracing on the GTX10 series? Pretty sure I have seen benchmarks of that showing...it was crap performance....well .. MORE crap then on the RTX series, but still they technicall could do it.
Hence im asking, but maybe there are other features that actually just dont work on them.

There is the need to have the actual hardware present for the developers and the gaming community.

Maybe software simulation which was shown on the aging Vega, too.

Does DXR 1.1 support need to be hardware for DX12U?

"all the ingredients needed for DirectX 12 Ultimate logo certification: software for DXR 1.1 ray-tracing, Variable-rate shading (VRS, tiers 1 and 2), Mesh Shaders, and Sampler Feedback. "

Apparently it only requires DXR via software.

Not everyone needss or even wants that RT nonsense.

Mesh Shaders? Variable Rate Shading?
It is also pretty clear at this point that hardware acceleration for RT will be a thing in the (near) future.

By the way, DXR 1.1 should be part of the next Windows release, meaning these drivers likely only work well with Insider builds right now.

TheoneandonlyMrK · Apr 17, 2020

Is there a application or game to test these driver's with the appropriate features.

Well sure, thats why Nvidia is there currently really, plus dev samples/hardware is quite different from having a product out in the market for people to purchase already, how do you think it works for consoles before you can buy them?

AMD set the stage with Freesync, then later Nvidia swooped in on that later with their Gsync compatibility, no problem whatsoever.

GoldenX · Apr 17, 2020

@Assimilator
It's not the first time it happens, Terascale never supported double float natively, and yet they got OpenGL 4.5/4.6 support via software emulation. It's not like Nvidia didn't enable ray tracing via emulation on older unsuported cards before, right?
Read a bit before commenting, please.

AMD used to be the innovation leader, with DX 10.1 for example.
Now, they are simply having their Bulldozer period with the graphics department. Years behind Nvidia in the graphics development.

It's such a shame!

Before that nvidia shader model 3 first, I do believe.

It alternates.

ARF said:

The confusion is probably that it does support it, but it's required to be hardware accelerated (it's not on Pascal).

GoldenX · Apr 17, 2020

Kind of a weird decision if you ask me. Force even the lowest end to support ray tracing, instead of just making it optional.

I guess no one will like 2-5 FPS on their entry level graphics card.

Kids will see "GT 3030, DirectX12 Ultimate, Ray Tracing", they will think it will run Minecraft RTX well. They will get a lag fest.

I don't even know what they are, so I'm pretty sure I don't need 'em.

Maybe, but I have to guess is the RT nonsense on or off if I compare different videos of gameplay footage. I don't see any difference, I see more difference by turning the details from high to very high/ultra.

VRS and mesh shaders are WAY more important than ray tracing, but since they get no press, people ignore them.
Mesh shaders changed the whole graphics pipeline we have been using since ever.

I still can't get how Turing is 2 whole years ahead of Navi 2X when DX 12U is a Microsoft's thing, with next-gen consoles development, also?!? :confused:

Actually, the current graphics pipeline with Unified shaders was introduced in 2007. Before that, vertex and pixel shaders till 2007.

RDNA1 seems like a rushed joke to try to get away from the Vega mess. It backfired badly, again.
