Your problem, I think on the strut which seems to bubble is due to your geometry: you should increase the precision of the modelisation
To avoid this phenomena you shoud apply a bevel around the perimeter of each hole of the strut in order to permit a good smooth. Each bevel should add edges...
I have just switched to Windows 10 edition 2004 and I confirm : my VRam data under P3D v5 goes from 3.9 / 6.7 GB to 3.9 / 7.1 GB. (LFOZ scenery from France-VFR,)
This change (more 400 Mo) is very beneficial because I have in addition more fluidity and the VRam is released more quickly.
A new slot reflectance appear in the SDK P3D v5 for PBR texture, this slot did'nt exist in v4.5.
Then this slot isn't use, the PBR seams more darker in the simu (not use => color black).

I'm sorry to provoke such a reaction from GSNDE but I've had access to the Alpha versions for 2 months and it's not a matter of liking or disliking but of seeing the current architecture of the simulator/game that brings me to this personal observation.
It is just my 2 cents ;)
To complement Matthias's superb sceneries (Project Africa), I wanted to try to realize Madagascar island. Two or three days to understand and try to make the Ortho4XP_FSX_P3D program functionnal and I launch my PC on this project last week.
I finished it yesterday. I use Ortho4XP_FSX_P3D...
