Hey Phil, I was just comparing the two screenshots DX9 vs DX10 and in the comparison shots it looks like 1/3 to 1/2 of the autogen trees are missing, could that account for the apparent FPS increase?  Sorry to be a thorn in the side just an observation...

Hey Dean, You were supposed to look in the upper left corner...and only there! And you were supposed to behold the skills of the developer team and the perfection of their methods to improve performance of FSX with DX10.

You were neither supposed to start counting trees...

Nor to point out the obvious possibilities of how to improve grafical realism in FSX, like applying realistic light to the simulated world and the objekts in it. That castle in the center is lit up like a polish brothel and as long as textures get bigger and bigger but are not realisticly influenced by the ambience light FSX will keep loosing performance and keep looking unrealistic...

Sorry for my enlish...

I still pitty the purchase.
