I got a big improvement in every situation over water, land and down low strafing London. Still the occasional hitch as textures are swapped in GPU Vram but 40-45FPS strafing London in cockpit view is a huge improvement. I have 64FPS external view at building level in London. Over water Im at 100FPS consistently.
I now also have all graphics options set to max including unlimited buildings with roads and grass on & shadows off with no AA. No SSAO and No Mipmaps @ 1920x1080.
Experimenting with different settings with the game paused in London at building level with an external view, shadows is the heaviest overall impact on FPS performance, Roads and Grass are next followed by number of buildings. AA is a big FPS hit for cockpit view but not so much external, seems the AA is pretty much limited to the cockpit details.
All the other settings only vary avg FPS by 2-3FPS each compared to 10FPS+ improvement by turning off various check box options. The trees and building details seem to effect the smoothness of play but not the overall FPS too much at least on my system.
With SSAO off and some coding optimisation for texture swaps, Mipmapping and texture sizes from 1C I think the issues can now be quickly resolved for the majority of users!
