Demo won't start - "DX12 issue"

[Bowling4Kleers]

Trying to start the demo gives me this error: "DirectX 12 is not supported on your system. Try running without the -dx12 or -d3d12 command line argument." There's no argument being given when this happens.
I run a windows 10 machine with newer hardware, so it should be able to run. Also, trying the "dx11" parameter in start options causes a launch crash, I sent over a log already.
Does anyone else have this issue?

This usually means your Windows does not have enough updates installed. Upgrade to 21H2 or 22H2, or enable Windows Update and get every update there is.

I am having this problem as well. I updated my Windows 10 (which was, admittedly, old) and my NVIDIA drivers and it still says it does not support DX12 even though it most definitely does for every other game.

Don't think it is. If min spec is a 970, then a 1660 should be fine. Log itself even says it supports SM6.5.

More likely the Agility SDK not found and the fact it is Win 10 2004 19041 is the issue. That's old Win 10 build even though he says he updated. Need to update it more than that - to 22h2 19045 ideally.

its literally the error in the log. Missing SM6

Shader Model 6 is the latest version of HLSL compiler technology. It is required for DirectX Raytracing, DirectML, DirectX Mesh & Amplification Shaders, and a number of other DirectX 12 features. The DXIL compiler (DXC) generates Shader Model 6 programs, and the compiler is based on LLVM and is hosted on GitHub.

For earlier shader models, HLSL programming exposes only a single thread of execution. New wave-level operations are provided, starting with model 6.0, to explicitly take advantage of the parallelism of current GPUs - many threads can be executing in lockstep on the same core simultaneously

It asks for all those requirements to be compatible with SM6 Feature Level due to Nanite and Lumen that requires them,

Update Windows to 21H2 or 22H2 and it'll work.

I was just clarifying his issue is out of date Windows so his solution is to update it. When you highlight the line saying his GPU only supports SM5 when SM6 is needed, it could give him the impression his GPU is out of date when that is not the case.

Update your OS.

Windows 10 22H2 is fine. But GeForce GTX 750 Ti is too old, you can't play this game without upgrading videocard.

I appreciate the update. I thought that my GPU was the issue here and was very upset because my 1660 should not be out of date according to the game's own specs. I'm not sure why I still have 2004 instead of 21H2 or 22H2 - according to Windows Updater itself, I was perfectly up to date, but now that I'm asking it to check again, it mysteriously has a whole list of new updates. I'm going to spend the night making sure that everything is up to date, and I'll check back when I'm finished!

[Liam Pope]

Yeah I've seen Windows updates being like that. Maybe it first finds minor updates for your current version, and only after that finds major updates? Might even need to go back in multiple times.

After a long adventure that required reinstalling Windows 10 (and thus all my drivers), I have finally gotten the game running! Thank you to all who commented, Talos Principle was one of my favorite games and I'm very excited to get into the sequel - cheers!

Appreciate any help. Thanks.

Sorry, you have "Intel(R) Iris(R) Xe MAX Graphics", meaning internal Intel GPU, which is not supported, as stated in system requirements on store page. :(

Will there be a patch or port in the future that will expand support to the Intel GPU?
