Thanks, I just wish I kept the same split layout so the transitions would have been smoother. :[

he is doing saveloading strat to save some time

The studder effect is basically me moving forward while quick saving and quick loading. It wouldn't studder as much If I didn't move at all, but holding forward helps me get to the end quicker than if I just stood still, and allows me to get a few more save loads off. The point of the quick saves and loads is as Maty said, it saves time throughout the level once the truck is activated. The truck is basically moving on a path towards the end of the level and I'm supposed to meet it there. Doing these save/loads it progresses the truck forward, I believe around a few hundred milliseconds per load. It may not seem like much, but add two or three dozen of these and you'll be saving multiple seconds. We found this works on other levels too that involve scripted objects. An example would be the third level "tram" where around six loads typically allows the activated tram to arrive just a little over two seconds earlier than it would without any loads. Cheers.
