IIRC you can find several rFactor 2 custom settings files done by other users in the Cloud Profiles section of the vorpX config app. Might be worth to check these out.
If the game (actually any game) looks zoomed in, you need to enhance the field of view (FOV). How that can be done varies from game to game. A list of general options in this regard is avalable in the Essential Hints Guide in the vorpX help.
For rFactor2 that is straight forward since it can be done directly in the game’s display options. The option is called “Vertical FOV”. A value around 90° should look right in the headset.
I’m talking rFactor not rFactor2 :)
NO 3D :(
