The framework traces its origin back to 2015 and attempts to fix and improve the state of Batman: Arkham Knight, Fallout 4, and Tales of Zestiria.

On top of this the framework includes a number of game-specific changes and optimizations that its developer have come across and fixed over the years, although minor ones are not always exposed to the user. The focus is primarily on the graphics pipeline but the tool also includes features such as input device blocking/configuring, window and volume management, enhancements for some of the in-game functionality of Steam, and more. Special K is an extensive game modifying framework allowing for various forms of in-depth tweaking of a game.
