MAIN section notes:

HandbrakeCamFix - this only affects handbrake camera when using a keyboard, with gamepad handbrake camera is handled differently and is too fast with high fps. No solution for that at the moment. Regular camera movement is fixed as well, which is too slow without this fix on high fps.

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.

FRAMELIMIT section notes:

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. Recommended 60 or lower, this option aims to fix the cutscene zoom that happens when playing on high fps.

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.

MISC section notes:

DefaultCameraAngleInTLAD - TLAD uses a different camera angle on bikes, this option can force the original IV camera angle. Enabled / Disabled

PedDeathAnimFixFromTBOGT - when you perform a counter attack after a dodge in IV & TLAD, the ped after falling and dying performs an additional death animation, which doesn't happen in TBOGT. Enabled / Disabled

DisableCameraCenteringInCover - see issue 20.

MouseFix - fixes small mouse movements not being recognized.
