What works

Gameplay, audio, save, load, cutscenes, all levels I've tried up to "Assassins".

What does not

Locks up about once an hour on my multicore system even with the schedtool fix described in the comments below (much more often without it). Hardware rendering is much slower than software rendering on my ATI HD 3300. Software rendering is fast but limited to 8 bit. Binding Alt+E to lean forward works to lean forward but clicking to use a weapon while leaning doesn't. Using an alternate keybinding without Alt works fine. Sometimes right clicking brings up a popup menu rather than working in-game. Sometimes sound stops working but toggling to the in-game menu and back solves it.

Additional Comments

Thief is an old game that will have problems on modern hardware, Windows or Wine. Therefore you must install TFix to run the game.

TFix might prompt a warning on language settings for the GOG version: you can safely ignore it.

Original setup

• Launch it with `wine setup.exe -lgntforce` to bypass the DirectX limitation warning.
• The Intel video codecs proposed at the end of the installation ("iv5codecs.exe") are no longer necessary with recent versions of Wine.
• Copy the THIEF/MOVIES folder from the disc to the game installation folder in order to play the game cutscene without disc.

GOG setup

It may prompt an error message at the end of the process. Do not confirm or it will revert the install. Kill wine instead.
