Sorry FSX

To start - there's an update to V2.5 already.
Prepar3D v2 Hotfix (2.5.12943.0)
So it "Fixes issue with Scenery Library requiring a restart" which was one of the problems that I had with V2.5.
But it now has GREAT looking ground shadows.
It may be that I just haven't had a location where the ground shadows were very dramatic, but judge for yourself.

I think that NOW Prepar3d has progressed, visually, far past FSX.
Prepar3D v2 Hotfix (2.5.12943.0)
The hotfix addresses the following issues:
Corrects issues with library object shadows
Respects effects flagged as on ground
Fixes issue with Scenery Library requiring a restart
Properly handles the cursor position in SimDirector’s text boxes
