I get this as well, but I’m using a legacy video card so there will be no more updates for it.
Was about to face not being able to map for a while, but remembered
use -d3d11 in the epic game launcher as a command line argument to force the editor to use DX11 mode
It runs, keep us going until the next driver update or saving up for a new graphics card
Old integrated GPUs cannot run the editor in DX12. They used to automatically fall back to DX11, but unfortunately we broke this behavior when we introduced DX12 performance mode in the client. We will fix the problem ASAP, but in the mean time the solution is indeed to run with the -d3d11 command line argument, to force the editor to start in DX11.
However, I’m not sure what’s wrong in Abu_Daxi’s case. A 2080 on Windows 10 20H2 should be able to run DX12 SM6, but the engine says this:
DirectX Agility SDK runtime not found
That means it cannot load D3D12Core.dll from INSTALL_DIR\FortniteGame\Binaries\Win64\D3D12. Can you please make sure this DLL is present?
