Change Number of Windows for Flip3D

On a default installation of Seven, the number of Windows shown for Flip3D is 10. However, on lower end video cards, this may tax the GPU a bit, resulting in slow or choppy visuals for Flip3D. But you can still use it! Just cut down on the number of windows that Flip3D displays. Pretty easy, really. The following is a registry hack which lets you change the number of windows shown when Flip3D is activated.

1. Press the Windows key on your keyboard.
2. Type regedit
3. Navigate to:
   HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
4. Right click on DWM and select New, click on DWORD.
5. Name the new DWORD value Max3DWindows
6. Double click on the DWORD value and set it to the maximum number of windows you want displayed in Flip3D. A good number is 5 for low-end cards and 10 for high performance cards.
7. Click OK and exit the Registry Editor.
8. Press WinKey+Tab to display Flip3D or download Winflog to launch it via the middle mouse button. You should now see the number of windows you specified in regedit!
