Hi Troy,
Not sure if the option to change this is in the demo (and most likely
isn't), however in the full version you can select the number of cars
drawn ahead. This will help those with lesser systems cope with the
extra CPU load.
BTW, that's a great price for IMO is a wonderful sim. Once you've
gone out and grabbed a copy, stop by The Sim Project site at the
address below, and you'll find a whole-bunch of neat utilities and
other enhancements to this fine game. =)
Best Regards,
Marc
