I was wondering if anyone knew if the optishot and 3dd software works on Windows 7 64 bit OS? Also, do you think it would run with an ATI Mobile Radeon 4200 series card? I've been thinking of getting the optishot and have been following this thread for a while. I had 2 Golf launchpads and they were crap to say the least and both of them broke within a couple of days. My 3 year old son broke the ball tether with one shot. Real piece off crap. I started looking for an alternative (under a $500) and found this thread. You guys are really helpful and really know your stuff. Any help would be greatly appreciated.
