Game loads and runs out of the box, except for controller configuration utility. Since DMC3 predated good controller support, configuration must be done with Steam or some external tool, which is not a small issue. It's not obvious which buttons and axes map to what in the game - for example, the L trigger on my 360 controller was mapped to the y axis of the left stick. Could be platinum if a controller could be configured with the game's utility instead of with guess-and-check outside the game.
I installed the protontricks AUR package and ran the command twice that several other users recommend. It generated some DirectX related errors on first run, but started anyway. Runs locked at 60 FPS with no issues on high settings, even on my outdated drivers.
I initially had the game crash on startup, and I had to either manually kill processes or reboot to even try to launch it again. Some combination of the following allowed it to work perfectly:
[1] "PROTON_USE_WINED3D11=1 %command%" as a launch option
[2]Use Proton 3.7-8
[3] Install the following packages: lib32-vulkan-icd-loader, lib32-vulkan-validation-layers, vulkan-tools (based on comments some people made about a vulkan error being fixed when they upgraded to 415 nvidia drivers)
Game also chugged for about a minute on first boot at the first loading screen doing its thing with shaders. Fine since.
