Hi all,I just got new PC and install FSXwhat i notice is when i fly with payware scenery such as aerosoft London Hetrow or frankfurt the performance impact is huge.i can fly on defult JFK with all sliders max with the PMDG 747x and get 30fps but with the payware addons kill the frame rate to 15fpsits lool like all the payware addons from FS9 that have version also to FSX impact the proformance because they didnt build from scratch to FSX.Does someone can fly with PMDG 747x in aerosoft frankfurt main (EDDF) and get 30fps solid?

Have a look here:

If you combine complex scenery and a complex plane, you are likely to get some slowdown.I certainly get a hit with Aerosoft's EGLL - I keep meaning to try the UK2000 version, since their other sceneries are very fps-friendly.If you want to see how it can/should be done, grab Fly Tampa's Kai Tak - unbelievable levels of complexity/detail, with fantastic FPS, even with complex planes. They do something special.

Have a look here:

hey i look at the video and i can see very poor anti alaising and also they used 2D cockpit and i use 3D cockpit this is a big different.
