Cliftor: I have it, but it's a headache setting it up on Vista. All I want is for it to work, in widescreen, with Darkloader.
But the faqs for that are vague, skip over details or sometimes just describe things that never happen on screen. They just aren't clear. Besides, even after it's all set up, some things are still quirky (fog doesn't work, for instance).
The Thief community is awesome, but they seem to lack the organization of, say, the Freepsace 2 Open crowd. Those guys have their **** down pat.
I would gladly buy it again at GoG, paying for the trademark convenience, compatibility and support (not that I bought it in the first place; I got it for free with a new video card way back when. Best freebie EVER).
I have it running on Windows 7.
Install 1.33 or 1.37 or whatever it is for Thief 2. Depends on which you have, obviously.
Run the DDFix GUI and choose your desired resolution, you can also run the video fix if you wish. DDFix will also fix the Dual Core issue.
Optimise with DarkLoader.
Play the game.
Unfortunately the same patch isn't available for Thief 2 because it bypasses the copy protection.
