I finally finished my newest build, supposedly for Flight Simming only.
Of course it had to be a Win10 system, more or less a straightforward operation.
So off I went with my plan, P3Dv5, P3Dv4 and P3Dv3(for CS Boeing's!)
Everything loaded as usual, followed by a marathon download of ORBX regions and scenery.

P3Dv5 loaded up and the results really ripped the crutch out of my nightie!!!!!!
I think I'll shut this down and go race some cars on the #2 PC!





It was the same at any scenario, partially corrupt surfaces, static aircraft and vehicles floating at various heights etc.
After running through the ORBX resets and verification's with no success a fresh installation repeated the exercise!!!!!
All drivers updated, no improvement, in fact v4 decided the Graphics were 'hung' and shut up shop!
Now this is running an i9 9960X at 4.4G, on a ROG Rampage VI Extreme Encore MoBo, a pair of Turbo GeForce RTX 2070 cards in SLI, with 128G of RAM, all on a 4TB SSD with the ORBX Libraries on a separate 2TB SSD.
I'll eventually sort it out but MSFS looks like a breeze!
