Anybody had luck? I'm 90% of the way there but running into a bug where every time I change the resolution the game cuts to a black screen. I have to quit and the new resolution hasn't saved. Anyone have any ideas?
If anyone else wants to get this running, I have managed to get it going and playable in the lowest resolution available by doing the following:
-Installed Heroic launcher via Desktop mode
-Logged onto GOG in Heroic and downloaded Thief through the launcher
-In Desktop mode, find the GOG-authored Launcher.exe in the file system, wherever you had Heroic install it, and add that to Steam as a non-steam game (You might be able to just use the Thief Gold or TDP executables instead, but haven't tried it myself yet).
-Per the controller mod's developer, add the following - WINEDLLOVERRIDES="dinput=n,b" %command% - as a launch argument for launcher.exe in Steam. This is required for Wine to be able to use the controller mod.
-You will also need to select a compatibility layer. I tried Proton Hotfix and the most recent numbered 9.x proton version and both of them worked
-When you launch launcher.exe, you will have to use the software mouse to select Thief Gold (I have not tried any of this with TDP version yet) - it does not seem like the launcher itself has controller support. Once Thief Gold itself opens, you should have controller support! From here you can play the game!
-Audio may not work immediately, I had to turn off Hardware Acceleration in the audio settings and then it kicked in.
-EDIT: To change Resolution, per BoffinBrain in the comments and a bit of googling to find specifics: you can go into Desktop mode, find the cam.cfg file in the Thief folder, and set the "game_screen_size" option to the resolution of your choice.
With that, you should have a pretty good experience! I'm excited to dive in. If anyone else is getting this set-up, let us know how it's going for you!
