I've been running it since the update was released.
Currently in P3Dv2.5
IMHO: The models seem to be much improved with more realistic looking skins, including reflective. LM textures are still a bit too bright for my taste. Models are LOD friendly, but still a big improvement. Airport parking looks more lifelike.
Traffic flow seems a bit more natural, but that may just be my interpretation.
DX11 working nicely, load times are quite friendly.
I would imagine that any of the skins could be enhanced in the same way aircraft textures are commonly modified. The entire fleet would be a wee bit of a challenge, but certainly personal favorites could be brought to a high level of detail.
Install was without incident.
All in all, I'm very pleased with the new version.
