Yes.

Here's what Lutris does for cyberpunk for example: https://lutris.net/games/install/30805/view

Creating a few directories, installing a specific version of MFC and running galaxy with some flags to skip incompatable launcher updates.

This is this not using the plain and simple C vkd3d (dx12) from wine but valve c++ dxvk. I still dunno why valve has not the decency to backport that into vkd3d, at least we would not need an absurdely and grotestely massive and complex c++ compiler, but the worst: it is using a ton of copies of windows DLLs from winetricks (I am better off installing windows).

I guess the win64 gog galaxy client does update the game to its latest patch.

Come on, nobody has to be proud of that.
