Ghostdog's PS:T UI Mod is a User Interface modification which in combination with the bigg's Widescreen Mod makes any resolution viable for Planescape: Torment by changing a number of things in the UI.
The Widescreen mod works extremely well in Planescape: Torment, but unfortunately when you change the resolution, almost all of the UI elements and game effects are shown in the top-left area since they were set for the original 640x480 game resolution. What this mod does is center all of these elements and enhance the UI with original game art to fit nicely with other resolutions.
Things fixed for new resolutions include many game screens including the Start menu, character creation screens, the journal, inventory, spells and stores among others, as well as a number of other components including the bottom UI bar which has been optimised, tooltips and in-game messages (which now display correctly), the dialogue box, and the worldmap.
The mod is compatible with both 2CD and 4CD versions of the game as well as Qwinn's PS:T mods, which can also be found here.
