Try this first...... if you have not already....

Set your preview resolution lower. PD renders your preview on the fly and on a LOT of computers it bogs down on transitions and effects. Even though you watch it at a lower resolution it will render/produce fine and the transitions and effects will be smoother. I have a decent computer but I still use the normal setting. Since I have used it for so many years... I don't need to see it in crisp clear HD preview. You wont either after a while... __________________________________________

When you are asked to provide a DXDIAG you go the following link and do part "B". Your posted specs are NOT what we are looking for as they tell us nothing. The specs on the box of your computer mean nothing. The DXDIAG shows us how your computer is configured as it runs.
