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?

Quoting from your logs @Singular Team:

So in short, there seems to be an issue with correctly parsing the "shader model 6.5" value; LOL. It IS in fact detecting the right card, not the internal one, as can be seen from the "Chosen D3D12 Adapter Id = 0", so it's looking at & using the right card / GPU (the D3D12 adapter 0: NVIDIA GeForce RTX 3060).

Basically, that means that the game is trying to detect whether your hardware is Direct X 12 capable, specifically, shader model 6(+). It tries to find a reference to shader model 6, but when presented the value "6.5" for it, somehow interprets that as "5". Thus, when it checks "are we at shader model 6 or higher", that gives back a "nope", and the game goes and poops its panties.

If I didn't know better I'd guess Croteam are just looking at the last character in the above "shader model 6.5", and therefore, marking it down as 5. Whereas it should be 6.5...

So yeah, oopsie for the devs then :D

Standard mistake if so, we've all done it at some point. Alternatively it could be a decimal separator ("," or ".") issue but I doubt it, these kinds of "system numbers" are usually standardized with a dot as the separator, I don't think it's a matter of locale/Windows language settings.

Windows 10 (Release 2004) [10.0.19041.450]

Agility SDK missing means either Windows release is too old or it's missing some updates.
Better update to 21H2 or later releases.

[therealsandor]

Note to self: read ALL lines of the logs next time. :P

[Singular Team]

As it turned out, this error is not limited to this game, and in my case it is related to the Agility SDK.
The advice to update Windows is correct, but with reservations - it is not necessary to install 21H2.
Agility SDK OS requirements:
If your OS Version is 1909, 2004 or 20H2, you also want to check your Revision Number.

For subsequent OSes this check will not be necessary.

The number appended to your OS build number, the Revision Number, gets incremented with each KB patch that your OS gets.

For Windows 10 Version 1909, the revision number should exceed or be equal to .1350 (as in the image above)
For Windows 10 Version 2004 and 20H2, the revision number should exceed or be equal to .789

https://devblogs.microsoft.com/directx/gettingstarted-dx12agility/#OS

Thus, after updating Win10 2004 to a version higher than .789, the game started

And yet I have a 6700xt running the latest adrenalin drivers. DirectX Caps Viewer says I have DirectX 12.1 and SM6.2, yet the log says I only have SM5.

Im running W10 build 1809 but I'm not going to update it just for a single game. You guys cant just not support slightly old operating systems or you're alienating a huge portion of your customerbase.

GeForce GTX 960M is below system requirements. It's a DX11-level videocard(feature level 11_0). This game requires cards with feature level 12_0 or higher.
Although it's similarly named to the min required GTX 970 but it's actually one generation older, Maxwell vs Maxwell 2.0.

Not just a single game, I heard some other UE5 games can't be played on older Windows builds. Expect more new games to be unplayable in the near future.

It's not an intentional alienating, old versions don't have a required component called DirectX Agility SDK. If you can install it somehow then go ahead.
According to https://devblogs.microsoft.com/directx/gettingstarted-dx12agility/ min required Windows build for it is 1909 and then you should have certain updates installed to reach revision number .1350.

Hey guys, same issue for me here. I try to load the game and get this message ""DirectX 12 is not supported on your system. Try running without the -dx12 or -d3d12 command line argument.".

It looks like your drivers are *very* outdated, try updating them and see if that helps!

Good morning as well. I dont want to post another thread as its just the same error, but I'm encountering this in Windows 11 instead.

I've tried updating all my drivers already but the error still persists. Any help is appreciated at this point.
