Slight improvement for me faster loading and fewer stutters averaging 70 - 80 fps oversea and 20 - 40 fps over land the worst being when first spawning in cockpit while everything is rendered drops to low teens then shoots back up after everything has finished loading.

another quick note is i can now actually fly over london before the patch i couldn't go near it due to extremely low FPS, FPS is still low (low teens) and would hate to have a dogfight there but it's a start
