Thief 3: Deadly Shadows, the third and last game in the first Thief trilogy. Developed by Ion Storm, the legendary company behind Deus Ex, and published by Eidos Interactive in 2004. 10 years prior to the reboot of the series. Technically Thief 3 is much better than the first two games. It uses the Unreal 2 engine instead of the Dark Engine, and the level design is much more detailed. Still, it struggles with compatibility on modern systems, but this update will make it run in any resolution and on any version of Windows. General performance & image quality will be significantly improved as well.

You might also want to change the screen refresh rate, if you run anything different from 60.
