-
AimingZoomFix - set to 1 for proper fix, so it behaves like on xbox, set to 2 to have this fixed feature enabled in IV and TLAD, set to -1 to disable this feature. 0 disables the fix, as usual.
-
FpsLimit - enter a desired value to specify the number of frames per second you want for the game. Like 30, 45, 60 or more. This will affect all gameplay.
-
CutsceneFpsLimit - enter a desired value to specify the number of frames per second you want for the game to use on cutscenes only.
-
ScriptCutsceneFovLimit - this is the minimum fov value the game can set during script cutscenes, like this one. It prevents the game to zoom in too much on high fps. Since it's not a proper fix for the issue, you may disable it and use hidden setting ScriptCutsceneFpsLimit that works the same way as CutsceneFpsLimit.

Fusion Fix uses dx hook to implement some features. It causes certain 3rd party software to crash/hang the game. To avoid this, Fusion Fix prevents certain dlls from injecting into the game's process.
