Wine Guide: Thief Gold
First we will create a 32bit wineprefix and then install a few things with winetricks:
WINEARCH=win32 WINEPREFIX="/home/user/wine-thief" winetricks vcrun2008 vcrun2010 winxp
Here I will install DXVK, though it is not required. What is required however is "TFix", I chose the TFix "Lite" version from the forum post.
I suggest the light version as the regular TFix adds: out-of-place hi-res textures, and changes how you play on some levels.
Now for some reason you have to start Thief using the start command rather then just running it with wine directly. That will look something like this:
WINEPREFIX="/home/user/wine-thief" wine start /unix "/home/user/wine-thief/drive_c/GOG Games/Thief Gold/Launch Thief Gold.lnk"
