First post. Howdy.
Are you using aa/af and vert. sync? I was having a heck of a time trying to get smooth, good-looking game play (specs below). In the game options I turned these items off (high quality, 1024x768) and went to the custom setting on my vid card. I turned all the bells and whistles up and it looked and ran great thereafter. I've put in about 10 hrs. of gameplay without a hitch. Probably just jinxed myself
Regards.
