No you did not try everything.

Do you understand what the Node placement does?
Obviously not.
Before you mess with the extended settings,
drop the Y position of the Node to -2.0 on Node 324 of the GWX Cameras.dat
THEN and only then do you start adjusting the extended settings.
Now can someone send me a stock GWX 3 Cameras.dat?
I whack this one to help you all without a back up.
