agsDriverExtensionsDX11_CreateDevice(...) failed

Development Programming & Scripting

The UE 4.18.3 is worked, but when I start Unreal engine 4.19, getting following error:

Fatal error: [File: …\D3D11Util.cpp] [Line: 233]

agsDriverExtensionsDX11_CreateDevice( AmdAgsContext, &DeviceCreationParams, &AmdExtensionParams, &DeviceCreationReturnedParams) == AGS_SUCCESS ? S_OK : E_FAIL failed

at …\WindowsD3D11Device.cpp:1152
with error E_FAIL

This function return AGS_FAILURE instead of AGS_SUCCESS. I found “exhaustive” description for this return code on AMD AGS site:

AGS_FAILURE
Failed to complete call for some unspecified reason.

There is a full log

I tried to reinstall UE, but it did not help.

Hope you can help me with this.

Just migrated to 4.19 and I’m having the same issue.

Find solution for this problem.

The reason of agsDriverExtensionsDX11_CreateDevice failed is that library, which integrate this function, support only
AMD Radeon™ GCN-based GPU (HD 7000 series or newer) graphic cards (from here). I had AMD Radeon R5 M330, which is lower.

So, the solution is to set graphic card which wouldn’t use AMD AGS library (any, but not AMD card), or which would support this library.
In my case, I have AMD Radeon and Intel HD, so I just disable my AMD Radeon in device manager.

UPD:
Was fixed in UE 4.19.1

I have an R7 360. I updated the GPU driver and that fixed the problem.
Now the engine works fine. Thank you !

This is a temporary silly solution.
I think that this is the omission of UE developers. They should check whether this AMD AGS lib is supported by a graphics card, and if not, then use the previous versions or something like that.

Perhaps, I am mistaken, and there already exists a clear solution to this problem.
