If you are talking about on a laptop the video card shares the memory for the computer rather than having it dedicated on the video card. By lowering the video memory setting you have freed up more memory for the processor which is where the syncronization has to take place. However if you do not have enough memory allocated for the video then that can cause problems too. It is a balancing act.
