Character models being backwards have been fixed on dxvks end and should be working once proton pulls in updates for it.
Providing a log for the wined3d game mode crash since that's the only real issue left now.
Hello @waspennator, using the PROTON_USE_WINED3D runtime option is not considered supported. If you want to pursue that crash further, then reproduce that issue with upstream wine, and follow up with the upstream wine devs.
Alright then, I'll just leave it at that and close the issue when the dxvk fixes come in then. Mostly brought it up since it works in desktop mode but crashes in game mode with wined3d.
Issue with backwards characters is resolved with Experimental, closing.
Game is now ready to be retested for deck support.

System Information
I confirm:
Symptoms
Characters face backwards during cutscenes out of the box using dxvk, switching to wined3d fixes this, but makes the game unable to boot unless you launch it in desktop mode.

Just start the game up, and go through the prologue and you'll run into it rather quick
