On my Windows 10 with DirextX and latest drivers installed i got message when i try to run this game: DirectX12 is not supported on your system. Try running without -dx12 or -d3d12 command line arguments.
Although the shortcut to the exe file does not contain any keys. Well I added -dx11 hoping it would launch, but got the message: Unable to launch with RHI "DirectX 11" since the project is not configured to support it".

I just wanted to check how UE 5.3 games will run on my old hardware. I have a Radeon R9 280x and an Athlon x4 860k.

Tried to install DirextX12 offline installer. But it didn't help, still the same error.

DX12 is key for all UE5 features to work correctly and I think it will struggle on anything but next gen GPUs. Without it, Im not sure it will work by design at all.
But this is why we have packaged the project with the video settings menu, so one can push even a potato if they wanted too. Im interested to see how it fairs on older tech. How old is no good? I think if the GPU is not DX12 compatible, then its really a ''best of luck'' situation.

My R9 280x is compatible with DX12 https://linustechtips.com/topic/346646-will-the-r9-280-support-dx12/

Also i can play recent games like Dying Light 2 in DX12 mode as well (but with performance issues). For example i can run fine Unreal Racing here https://kronbits.itch.io/unreal-racing

So can you not get it to start at all?
