Do you have experience with opening windows using different graphics adapters as primary (not monitor, graphics card).

I've been looking for a fix for the dual view performance problem, and I recall on another thread Lax posted that IS can specify the adapter when launching a window (so directx loads the resources on the adapter the window is being displayed with).

A workaround is to manually change your primary display in windows, run wow, change primary, run other wow. I'm curious how IS does it. I was doing some poking around to see how I could extend something like maximizer to do this without manual steps, and the only thing I arrived at was using windows GDI functions to modify the display properties (ChangeDisplaySettingsEx) to set the primary display before launching each wow.exe.
