The Problem:
When attempting to launch Unreal Engine 5 with DirectX 12, the following error prevents startup:
This project attempted to launch DirectX 12 with the SM6 shader format but it is not supported by your system. This will prevent advanced rendering features like Nanite and Virtual Shadow Maps from working.
The Conflict:
My system reports support for the required features, yet the engine rejects the hardware:
-
Hardware: 12th Gen Intel(R) Core™ i3-12100 with UHD Graphics 730.
-
Reported Shader Model: 6.7 (visible in Intel Graphics Software).
-
DirectX Support: Feature Level 12_1 is supported by this hardware.
-
Driver Version: 32.0.101.7084 (Latest WHQL).
Technical Log Data:
Upon investigation of the Windows Event Viewer, I found an initialization crash occurring during the engine’s hardware check: {"category":"Igcl","level":"Error","message":"3rd Party - IGCL ctlMemoryGetBandwidth - Exception"}
The engine fails to initialize the RHI in DX12/SM6 mode despite the driver claiming compatibility. The project only opens to -d3d11 .
