So far I'm not impressed with the jerkiness of simulations frame rate. I have a fast computer (pentium d 950 3.4Ghz with 2GB ram and ATI x1800 512MB ddr3 memory). I have played with the graphics settings turning everything down to low but I just can't get a nice smooth frame display. Is this just the way it is in FSX or is there some other settings I can tweak. For me the realism of the sim comes from an ultra smooth frame display. If it is at all jerky or stuttering the realism is lost for me. I am running windows XP professional with the Flight Sim X Deluxe version.
