I get a lot of lag when using this product. The sim would pause/lag for 1/3 seconds  when I move the mouse pointer across the screen. This is more noticeable in windowed mode. I use rex direct textures, active sky next, ezdock and aivlasoft efb all running at the same time. I have a 8350fx asus sabertooth 990fx, 8gbs ram msi gtx 670 my gpu and cpu is not overclock. I doubt that this is a hardware issue but I could be wrong. uac is disable on my pc but I still installed with administer. rights, fsx is also run as admin. I also made sure that the soft was setup properly according to the manual . My os is win 7 64 bit, I need help please.

I would ask the FSX general forum.
