Hi Pat
With photogrammetry enabled, the bumps are very softened !
But the proximity of New York in photogrammetry, divides the performance by ... 2 !
Photogrammetry is very pretty, but activated, the performance is divided by 2... KJFK without Photogrammetry, I have 20 to 30 Im/sec...
with photogrammetry activated, I falls below 10 Im/sec !
This is the reason why I use MSFS with photogrammetry OFF ! ( And I think many other users too ) !
I have almost 200 add-ons, none of which require me to activate photogrammetry so as not to have runway problems <:\ !
But I d'ont no, why photogrametrie modify the altitude of the ground <:\
