I won't profess to be super knowledgable about this kind of stuff but here is my issue. 

In my computer there are two graphics cards ( AMD Radeon HD 7730M and Intel Mobility 4000) they are controlled by the switchable graphics menu where you can assign an application to use the high performance or power saving graphics processor.

Now i assume the high performance is the AMD Radeon and the power saving is the Intel? 

The question I have is when trying to run Trine (quite an old game) the game is super laggy and unplayable when assigned to the high performance graphics processor but runs smooth and on the highest settings when on the power saving graphics processor. 

How come this is happening?  The laptop is plugged in when gaming and the drivers appear to be the updated versions!

Here is a good article from HP explaining the various properties of 'switchable' graphics.

I guess my quiery is why does the game run better with a power saving GPU rather than a high performance GPU?
