I like to mention, that Helsinki photogrammetry is now flyable on my mediocre machine.
I get 20+ fps alltheway with the whole package etc. everything installed in msfs SU5 hf 2.
My specs: i7 4790k 4,2 Ghz, 32 GB of ram ddr3 1866 Mhz and GTX1080ti and SSD 4 TB
Scenery got bad reviews, because of total abysmal performance, now its smooth on ultra even.
