May I ask you to create some patch to run UE4 on slow gpu’s?
Here’s report, the main problem I believe is
LogD3D11RHI:Error: Direct3DDevice->CreateShaderResourceView(Texture2D->GetResource(), &SRVDesc, (ID3D11ShaderResourceView**)ShaderResourceView.GetInitReference()) failed
at D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.0\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Texture.cpp:1118
with error E_OUTOFMEMORY
