Hi Chris, "ZoomApproachTarget" means it will move by a fraction of the distance to the rotation pivot point like how mouse zooming works.

Is it the zoom speed only that you're having trouble with? You might try setting Options > View > 3D View projection = "Parallel" since zooming in a parallel projection view is much simpler than in a perspective view.

What do you mean by the "1.0 parameters", are you editing the speeds in the moi.ini file directly? If so then MoI v4 uses new settings in there:

RotationSpeedV4=1.0
PanSpeedV4=1.0

the settings under:

PanSpeed=1.0
ZoomSpeed=1.0

are not used by MoI v4 anymore so there won't be any effect from setting those ones.

You can use the UI under Options > View > Rotate/Pan/Zoom options > 3Dconnexion options > "Pan speed" and "Zoom speed" which should set the right ones.

The new settings are used in v4 because the default speed was changed in MoI v4 and so the speeds set for previous MoI versions are ignored and new ones used instead.
