Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Is it possible to package a game with DX12 exclusively?

Hello guys. I have made a demo to test the performance of dx12 in UE4 and I would like to package (ship) this demo for testing on other PCs. I've tried several ways yet failed.

  1. Launch UE4 in DX12 mode with -DX12 and package When I started UE4 in DX12 mode I could tell from the log that the RHI was assigned as DX12: LogD3D12RHI: Chosen D3D12 Adapter Id = 0; LogD3D12RHI: Emitting draw events for PIX profiling; LogD3D12RHI: The system supports ID3D12Device1; LogD3D12RHI: The system supports ID3D12Device2.

    However after shipping, the packaged demo still runs in DX11.

  2. Launch UE4 in DX12 mode & In Project Settings - Platforms - Windows untick DX11 and DX10 (no DX12 appeared in this section) Still, aftering shipping, the packaged demo runs in DX11.

Many thanks!

Product Version: UE 4.20
