For me, it gets to a screen asking whether I accept some terms, and then a seemingly never-ending black screen with all of my CPU cores sitting at max usage.

Works on my end on Proton 5.0-7, but very slow (near 2 fps). But works great on Proton-GE 5.8: https://github.com/GloriousEggroll/proton-ge-custom/releases/tag/5.8-GE-2-MF

Specs:

• Nvidia 1070, driver 440.66.08
• Ryzen 5 3600
• Archlinux, kernel 5.6.13

Proton lacks upstream patches that makes Detroit to run performant.

https://bugs.winehq.org/show_bug.cgi?id=48291 sounds like it's very much a hack though and a generic solution isn't easy. As I understand, the game (just like RDR2) does some low level syscalls which are difficult to replicate/intercept or something. At least in a way that's still performant.

@DanMan Yes , that is why a there is a proposal like this for Linux kernel now.

Making changes to the kernel is a long process, I guess. Could it be easier to make such changes to an existing SteamOS kernel?

Thanks for the workaround using Proton-GE 5.8! :heart: Works awesome! :smile:
