Windows 7: Classic Desktop Redraw Problem

The other thread for this topic is way back in 2009.



When dragging a window over another window, there is a delay in redrawing the window and I can see the (dual core) processor working harder.
Why is hardware acceleration turned off for the classic desktop and is there any way to turn it on?
Aero Desktop works fine.

I don`t want to turn off "display windows contents while dragging", that would be like going back to windows 95!

The only alternative I can think of, is to try and setup an Aero Desktop with the Classic Desktop Metrics.

Latest ATI 12.1 Driver installed (13.1 is not for the card I have).

DxDiag results.
ATI Radeon HD 4600
Driver 8.970.100.3000
DDI Version 10.1
Driver Model WDDM 1.1

DirectDraw Acceleration: Enabled
Direct 3D Acceleration: Enabled
AGP Texture Acceleration: Enabled


Thanks.
