If you use a graphic card that doesn't support Vulkan no title will launch on Proton, but it will do seamlessly on Wine.
The work-around for this is to manually instruct Proton to use Wine3D instead, by adding the following launch option to each game:
PROTON_USE_WINED3D=1 %command%
This would be better detected and set automatically.
