Started using this recently and quickly hit a snag; I'm using an AMD RX 480 and although DXVK shows installed, none of the games that require DirectX are functioning unless I launch with the launch option "PROTON_USE_WINED3D=1 %command%" to launch using OpenGL instead of Vulkan, and even then there's a handful of games that I haven't managed to get working (still getting protontricks set up). I'm not really sure what this points to, if I GPU passthrough to a VM I don't experience these issues.
E: Did some more tinkering, looks like for some reason it's just the GE-Proton and Experimental builds at fault; switching to a stable build fixed it.
