"DirectX 12 is not supported" Error But I have DirectX 12!

[Loot Hunter]

Can't play TTP2 demo on my notebook because of the "DirectX 12 is not supported" error.

System:
13th Gen Intel(R) Core(TM) i9-13900H 2.60 GHz
16 Gb
Intel(R) Iris(R) Xe Graphics
Windows 11
DxDiag says that DirectX 12 is supported

I don't know if your hardware is above minimum specs since I'm not that familiar with the technical details, but it seems fine by what I could find. If it is, make sure your graphics driver is up-to-date. There is also a whole thread about this error message, so a new one is not needed. Post your log files if you still need help.

Is it integrated? I found something about a dedicated GPU with that name.

The Intel Iris Xe GPU is typically found inside new mobile Intel CPU's, so yeah that's typically an integrated Intel GPU (more powerfull than previous generations but not enough for this game).

Intel Iris Xe in this case is an integrated GPU. Intel Core i9-13900H has an integrated Intel Iris Xe Graphics 96EU: https://www.techpowerup.com/gpu-specs/iris-xe-graphics-96eu-mobile.c4145

Intel Iris Xe MAX mentioned in the link above should be dedicated but I don't know the exact conditions why it's not supported. Does it not have enough VRAM? Or drivers don't support certain features?

[puddingtopf]

The Xe MAX has 4 GB of VRAM, but I suppose OP is using a laptop with integrated graphics.

My pc is trash and I accept that it can't run this game, but honestly, judging by the various responses, it feels like A LOT of hardware is not supported by the game

(just in case you don't know, right click a game in your Steam library, and write "-vulkan" in the command prompt. If the game is compatible, it will use something else than DirectX, which is useful. Similar to OpenGL).

It doesn't work in general, only for games that have certain engines.
-vulkan, -dx11, -dx12, -opengl are for Unreal Engine 4/5 games.
-force-d3d9, -force-d3d11, -force-vulkan, -force-opengl for Unity games.
-dxlevel nn for Source games.

The game reacts to "-vulkan" , and it says the following message:

"Unable to launch with RHI 'Vulkan' since the project is not configured to support it"

I ask the Developers: Will it be implemented then? For the Demo or for the full game?

Given the DirectX12 issue, I would like to be able to play, and Vulkan implementation seems like it might help.

Nope, no Vulkan support, sorry.

Yes, a lot of OLD(ER) hardware.

Even Voodoo gfx cards are not supported! ;)

What would help people is to write what Feature set of DX 12 is required.
DirectX: Version 12 <- this isn't enough.

[MASTAN]

Besides feature level 12_0 modern drivers are required. Old D3D12 AMD hardware is considered obsolete by AMD and they have outdated drivers without required features.

Nvidia's first D3D12 gen which is GTX 9xx is fully supported still.
