Photogrammety has been fixed yesterday evening! For the first time since January I can fly through New Yort with PG turned on and all buildings and streets are there with all their glory!
Since SU10 the PG was too slow even for scenery driven challenges. Before (SU8 and SU9) big cities like New York were a nogo. SU11 initially broke the PG completely.
Now, PG is fully functional and fast! Thank you, Asobo!
