As the title states, I'm wondering how I can get more FPS out of FSX. Yes, I know that there are several videos out there. I don't want to sacrifice too much airline traffic density. I also don't want to sacrifice much in the way of scenery, but I need something better than what I'm getting right now at busy airports. At an airport such as KJFK, KDFW, KBOS, or KATL, I get about 5-15 FPS in my PMDG 737, and when I'm approaching airports such as these, I often get a message that says that I ran out of memory and that FSX will now quit.
My system specs:
Windows 10 64-bit
Intel Core i7-4770 @ 3.4 GHz (quad core, 8x logical processors)
8 GB memory
1 TB hard drive
NVIDIA GT 640 with 2 GB video memory
I know that the video card is what limits me. Any advice and tips are appreciated greatly.
