WDDM 2.2 in Creators update and drivers

Nope, everything running smooth here. I was on the fast release upgrade as well, but I did a clean install on Thursday since the RTM is already out.

Try using DDU to do a clean install of the drivers, then reinstall.

 

HDR10 and/or Rec2020 can be supported on old Windows through proprietary driver extensions, Win10 just offers a standardized way of doing it.

What does ME Andromeda use now? (I can't tell, I am not a "Frostbite insider" and I don't have an HDR10 display but I know it supports HDR10.)

---

I personally hoped the UHD era with ITU HDR10 and DolbyVision will finally bring 10-12 bit/color support to old SDR devices (obviously with mapping the output to Rec709 at ~120nit but keeping the higher gradation).

My video cards have been feeding my old TV with 10 (and recently even 12) bit/color through their HDMI output for many years now (DeepColor was a widely adopted standard in the FullHD era, at least among display manufacturers at basic compatibility levels). It's just that no PC software ever cares (with a few small exceptions like madVR for media players or the Alien Isolation game) to pass 10+ bit to the display instead of sticking to 8 bit.

Sadly, it seems UHD HDR10/DV10 changed nothing in this regard. More and more games will support HDR10 while ignoring 10+ bit/color for SDR. I can't even trick them into outputting HDR10 to an SDR display and let me process their output with ReShade (to convert from Rec2020 HDR10 ~1200nit to Rec709 ~120nit while keeping it 10 bit/color ; or even use the actual display profile which can exceed these SDR specs by ~120%).

 

NVAPI.

Yeah, that was my hope as well but alas you're right, the only way to get WCG in 1703 is if you have HDR10 display. And even then it seems to be broken on the desktop at the moment.

 

Btw, here's whats D3D12 Feature Checker shows for GTX1080 on 381.65 drivers in 1703:

So no SM6 support in the driver yet.

 

So far, Shader model 6.0 is enable only in experimental mode all IHVs drivers.

 

Does it work there? I thought that DXIL compiler is still missing.

 

DXIL format is done, it is part of the last Windows 10 update.
As for driver conformity and compiler stability you can have a look at the official github repository: https://github.com/Microsoft/DirectXShaderCompiler

 

Hardware GPU support for DXIL is provided by the following vendors:

NVIDIA r378 drivers (r378.49 and later) provide experimental mode support for DXIL and shader model 6. This is an early beta version to enable developers to try out DXIL and the new shader model 6 features – Wave Math and int64. Only DXIL version 0.7 (beta) is accepted by the r378 driver. Experimental mode support for DXIL v1.0 will be provided in a future driver release.

+

The NV r381 driver branch supports DXIL 1.0


So it should work in experimental mode on NV h/w. I wonder how far we are from production release though.

 

For check HLSL Shader Model 6.0 need get members WaveOps (bool type) from D3D12_FEATURE_DATA_D3D12_OPTIONS1 structure

Code:

#include <iostream>
#include <wrl\client.h>
#include <d3d12.h>

#pragma comment (lib, "d3d12.lib")

int main() {

	Microsoft::WRL::ComPtr<ID3D12Device> device = nullptr;
	D3D12CreateDevice(nullptr, D3D_FEATURE_LEVEL_12_1, IID_PPV_ARGS(&device));

	D3D12_FEATURE_DATA_D3D12_OPTIONS1 data = { 0 };
	device->CheckFeatureSupport(D3D12_FEATURE_D3D12_OPTIONS1, &data, sizeof(data));

	if (data.WaveOps) std::cout << "HLSL Shader Model 6.0 support" << std::endl;
	else std::cout << "HLSL Shader Model 6.0 not support" << std::endl;

	std::cin.get();
	return 0;
}

Spoiler

By the way, Intel Iris Graphics 580 don't support WDDM 2.2 (driver version 22.20.16.4729)

Spoiler

 

I don't think Intel supports WDDM 2.2 on any Skylake iGPU (yet).
