Specs, & where you have it installed... look ok....
Relooking at your mods list...
is ringing a warning bell, with "GWX - English Nav Map and Grid Refs"...
Seeming to recall that there is 1 of the other mods, that is NOT supposed to be used with GWX - English Nav Map and Grid Refs...
or that other mod in conjunction with GWX - English Nav Map and Grid Refs...
Only thing is... can't recall the name, of that other mod... & don't have GWX3, installed, so I, can't read the manual for it. Thought I might have, still had that manual... which is why it took a bit for My reply back now.
I'll see if I can find that info... that is, if another doesn't beat Me to it, 1st...
