Here's my latest wallpaper, done at 5.00am in game to show some landscape shading.
I haven't measured fps, there doesn't seem much point over land!
Game is playable (just!), with just a few stutters, on very high settings with 8xAA over water, I'm using the Bomber Intercept mission with no clouds at 7pm as my 'black death'.
Lowering the settings or screen res doesn't seem to have any effect at all!
Any overland missions are not playable at any settings or resolution.
Am about to try the processaffinity=15 trick.
We'll see.
