UE 5.7 Preview -> DX12 Broken on AMD 7900XT Driver 25.10.12 Released 10/13/2025

Hello again, just an hour later.

Next issue, just asking around here if anyone else came across the issues / had a workaround before I make a Bug report.

Updated to 5.7 as I heard Chaos Caching issues mostly disappeared in 5.7. Also considered Downgrading.

Engine Version 5.7 doesn’t even start. It crashes due to GPU error on DX12. Changing in config to DX11 works fine. Vulkan works too, but takes a lot of time for compiling shaders. Might be a one time thing, DX11 and 12 were a lot faster at first compilation.

Does not happen with 5.6.1, 5.5.4, 5.4 or any other version I tried so far.

Anyone else?

I got same Issue on 5.6.1 do you got any solutions?

Solutions not, workaround yes. Interesting that it happens on 5.6.1 too though because there I do NOT have that problem.

What is your GPU + Driver version?

Workaround for me:

DefaultEngine.ini → search for the windows settings → Replace the two DX12 entries to either “Vulkan” or “DX11” at the end of the snake case formatted string.

DefaultGraphicsRHI=DefaultGraphicsRHI_DX11
DefaultGraphicsRHI=DefaultGraphicsRHI_DX11

Like this or this>
DefaultGraphicsRHI=DefaultGraphicsRHI_Vulkan
DefaultGraphicsRHI=DefaultGraphicsRHI_Vulkan

Or:
Start Unreal via shortcut and add -vulkan flag or -dx11 or -directx11

my gpu is same 7900xt i downgrade driver to 25.9.1 its working but my friend has 7900xt to its not work for him and also tryed vulkan but vulkan have very low performans
