I installed it, but his readme indicates you can choose between Photogrammetry and Hybrid, but I’m not clear on how to enable one vs the other. As you can see, the Monasteries themselves are Photogrammetry, and a bit blurred at close distance; they look much better with a bit more altitude.
I’m not criticizing, they look much better than the Bing (Autogen?) buildings although those have more structure as polygons. It was still an improvement over the default scenery.
Note: if you start in mid-air using the Long/Lat coordinates in the readme, it’s possible not all your instruments (esp. if you’re in a glass cockpit) are working. My right hand Garmin was blank/shutdown, had to climb out and do a mid-air engine restart to get everything booted up.
