Severe Trackball Lag

[yamo]

I've looked everywhere and I can't seem to find any solution to my problem. I have 2 identical cabinets both using the U-Trak trackball from ultimarc. The trackball functions perfectly fine in windows and in gameex but when I go into certain mame games it lags up the entire system. One example would be

golden tee 2k, going into this game the trackball functions for about 3-4 seconds fine. Then after that the entire game lags, if i spin the trackball it can take anywhere from 20 to 30 seconds for anything to happen. When I push escape to exit the game it also takes 30-40 seconds to exit. This happens in about half of the trackball games.

I've tried hitting tab to go into the controls and ive set every X and Y axis to the trackball but it doesnt help at all. I know its not my PC lagging because its a fairly speedy system:

dual core e5200 @3.75ghz

2gb ram

9600GT

using MameUI

I've run out of ideas please help!

Well amazingly I just figured out the problem! I'll post it here incase anyone else is having the same problem. Apparently the culprit was frameskip enabled and/or vsync. Turning those off fixed all my problems!
