Lately I'll been having problems with synch errors popping up and down, so i thought ill research some tips for it.
Usually the error has something to do with yr screen sizes not matching up, so if you change it to 1024 X 768 on yr options it should help.
Here are some other tips it that doesn't work out.:
Use Cat 6 Cable, not 5
Check the number of pins on your monitor cable. For example, a lot of Dsub 15 monitor cables actually only have 14 pins when you check them!!! Frys Electronics has them with the FULL 15 pins for $4.95ea.
Set all your video cards for SPEED or PERFORMANCE, NOT quality.
if this doesnt work download this and put it in C:\Program Files\Microsoft Games\Age of Mythology

HAPPY GAMING!!!!!!
