First of all i'd like to say hello to all the users of this forum. I am brand new to GameStudio.

Just a quick mention about myself: I am 19 years old, from Australia, and am currently studying a Diploma in Games Development. My final assessment is to create a video-game prototype with my classmates. I am the project manager and lead programmer for the project.

i'm having a few issues with my buggy and the physics engine. With the help of some excellent tutorials and the Racer Demo I have got my buggy driving around my level. but i'm not entirely happy and don't know what to do to fix it up!!

Here is a 60sec clip of my Beach Buggy driving around a test level:
60sec Clip

I am having two main problems (visible in the clip):

1. - The buggy jerks around (fps calculation problem??) but on occasion it completely stops as if it has hit a wall (See video clip @ 5-6 seconds).

2. - The wheels seem to really throw the vehicle around when it turns. As you can see at the beginning of the clip how the buggy sways whilst it turns.

Any suggestions on how I can improve the movement? This is the best results I have achieved so far without the buggy rolling or spinning out of control.

Thanks in advance!
