Hi all I have had no problems FPS on the full 757 4.1,I have a AMD6400+3.5gig mem 8800GT 512mem,FSX+sp2 Vista 32bit I get about the same FPS as with other 767 + other 747-400x. At TMCM all slidders to the middle i get 28fps mark

Can you give a bit more information about your hardware spec? As you can see, it's similiar to mine (don't take Gfx into account - it has little to do with FSX) - info about mine is in my sig.
Also, do you have Block F? I have everything for CS 757, but 757-300.
What's TMCM ? I couldn't find such Airport ID, in any online database, nor in the FSX.
Would it be possible that you post your fsx.cfg file, so I could check your config against mine?
Thanks in advance.

Cheers.

PS> I think I've found a pattern in fps drops - it seems that the greatest drops are when plane is just starting to roll to takeoff.
