As of May 16, 2020, using Proton 3.16-9, TrenchesWIP works without any faults, errors, or compatibility issues, and with no noticeable performance issues. No added Launch Options are required, although I have seen someone mention on ProtonDB to use -dx11 as an option if it does show anything about issues with DX12.

Symptoms
When trying to run TrenchesWIP using Proton 4.11-11 on Ubuntu Linux, a pop-up appears saying "DX12 is not supported on your system. Try running without the -dx12 or -d3d12 command line argument." I tried to Set Launch Options to
PROTON_NO_D3D11=1 %command%, and it results in no more pop-up warning, but it only shows it's running for a few seconds, but then never starts and goes back to the Library - that is the log attached. The pop-up appears with PROTON_USE_D9VK and PROTON_USE_WINED3D options separately.Reproduction
Force TrenchesWIP to use Proton 4.11-11, or any Proton version - tested all available in options with same results including Proton 4.11-11, 4.2-9, 3.16-9, 3.7-8.
