Hi All,
Not sure if you guys are aware of this but there's been an announcement regarding V4 of Prepar3D
Looks like they're releasing a 64bit version pretty soon (30th May!)
I think I'm going to wait this one out until I know more about it, I have way too much in the way of aircraft & scenery, I'm dreading the fact that they will probably more than likely be incompatible.
