Possibly.
Unfortunatly, the changing and swapping of multiple windows is not always as
efficient as we would like. This tends to be more of a problem on
the high-end machines where the complexity of the state in the
graphics pipeline complicates the multiple window/gfx context case.
So, you should try to use multiple channels whenever possible/appropriate.
If you are using multiple windows and are texturing, you'll want to
be sure to share the GL objects (textures and display lists) between the windows.
See the pfPWinShare reference page.
