I'm getting the "DirectX 12 is not supported on your system. Try running without the -dx12...

DirectX 12 is fully backwards compatible with DirectX 10 and 11. DirectX12 is already on both Windows 10 and 11. DX12 Ultimate is of little use unless you have a high end AMD RX 6XXXX or NVIDIA 20XX or better graphics card/discreet graphics processor.

DirectX is software that works with your graphics hardware. If your graphics hardware does not fully support the hardware level of the version DirectX of the game you want to play, you can't play it.

For example, even though your PC/Laptop has DirectX12 installed, if your hardware only supports DirectX 10, you won't be able to run games that require DX11 or DX12.

If you could provide the system specs of your machine, we could have look if your hardware is compatible with War Thunder. Without this information there is no way to know.

Hi That1F1Kid,

Thank you for posting in Microsoft Xbox Community. I understand that you want to play Rennsport on your laptop. However, you're getting an error message about direct X 12 not being supported on your system.

This is because the Intel Graphics that you have is does not meet the minimum system requirements of the game. Because your hardware capability is limited, reason why you are receiving the error message.

If you have a dedicated graphics card such as Intel Arc, you may go to "Graphics settings" , click on Rennsport and set the GPU preference to "High Performance" then try playing the game.

I hope this answered your question directly and removed any confusion that you may had.

All the best,

Alvaro

what GPU do you have, AMD what. as the OS is directX 12 but the GPU must support DX12 too.

thanks, is there somthing i can do about it?

ive now chacked and intel arc a750 does support directx 12, i also run dxdiag to be sure and it showed me i do have dx12.

Hi, Hajaan.

Thank you for posting in the Microsoft Community.



From your description, I understand that you want to choose DX12 in some games that support both DX11 and DX12, but you can only use DX11. I understand your confusion about this problem.



You mentioned that in some games, even if you can choose DX11 and DX12, the game can only use DX11. This may be caused by the following reasons:



Optimization and support of the game itself:

Not all games fully support DirectX 12 Ultimate. Even if the game allows you to choose DX12, some old games or developers have not fully implemented all the features of DX12 Ultimate, resulting in them not fully utilizing the advantages of the hardware when using DX12.



API limitations or game engine issues:

When switching between DX11 and DX12, some games may not run stably enough on DirectX 12 due to the underlying engine architecture, compatibility issues, or optimization during development, and then fall back to DX11.



We look forward to hearing from you!



Best Regards.
