Camera lag, any suggestions?

Recently I’ve been trying to get back into Age of Empire III but I’ve noticed that I get a pretty noticeable lag. I don’t think it has anything to do with the FPS because if I keep the camera still, everything on screen (including the mouse) runs pretty smooth. I’ve also noticed that if I move the camera over an area a second time, the lag seems to reduce/disappear. Has anyone else run into this problem?? I’m currently using a disk copy of AOE with all the expansions, fully updated. My comp’s specs are below (drivers fully updated), the only other time have had this kind of problem is on another desktop using an NVIDIA card (AMD cards, from what I can tell, don’t seem to have this issue).

Thanks for any suggestions!

Hmm, try toggling windowed mode in the game settings.
