The only problem Deeter is it is not everyone is having this problem.

James is this an Intel or AMD processor?
Laptop or desktop?
How much memory does the ATI have? What model is it?
Have you done all the changes listed for Windows 7?
Have you tried turning off unneeded processes using Blackviper's recommendations?
Have you tried lowering the aceleration for the audio through the DXdiag?

So what you are saying is MTU should not have put in all the requested upgrades that users have asked for? They have worked very hard trying to get this program as good as they can. Microsoft has thrown so many monkey wrenches into the works with the major operating system changes of Vista and Windows 7 that it is hard to keep up with all of it or find out from them what all they have changed.
I know that the military had a policy in place that any major change in operating system had to have gone through rigorous testing and at least 2 service packs before they would even think of using it. Vista never made it to two and Windows 7 hasn't had one yet. IMHO that is where your program code errors are.
