Special K for FFXV is a mod for Final Fantasy XV: Windows Edition, created by Kaldaien.
This mod fixes a lot of issues and performance problem
The game loads input icons synchronously any time it sees input on keyboard/mouse or gamepad. This means if you are using a gamepad generally but you hit a button on your keyboard -- hitch. If you use keyboard/mouse but hit the analog stick -- hitch. This mod is capable of working around this by preventing the game from seeing input events on devices of your choosing.
This mod also includes fix thread scheduling on the most important (least important, actually) threads. Having these scheduled incorrectly is responsible for:
Increased load times (as is SteamAPI, as is anti-debug ..... Square-Enix hates us)
Extract to FFXV's install directory, done.
