I have KMEM in FSX and performance there is quite good, even with all the eye candy turned on, minimum FPS of about 26. KSDF on the other hand is far worse, around 13fps, and as low as 9fps depending on the view direction! Are there any settings I can change to improve it? The control-F12 settings only have 3D cars and ground traffic. Both of those are already disabled, and strangely even with them enabled there isn't a big change in FPS.
By comparison, I have P3D v4.4 installed as well, and while KMEM performance is roughly similar between FSX/P3D, KSDF is vastly different in P3D, peforming smoothly in P3D (about the same performance as KMEM or even better) but very poorly in FSX. That's even in the PMDG 747-400 which is FAR worse on the frames on my PC than the MD-11 I use in FSX.
Thanks in advance!
