Description
The `VTK RenderWindow` class has a `SetDeviceIndex` method. I can't find any equivalent in MayaVi/TVTK.
When I do not have my laptop connected to its hardware dock (you know those things you set your laptop on and it gives you lots of connections you wouldn't otherwise have had) I have getting abysmal performance (1 FPS).
On the other hand when I am connected to my hardware dock I have great performance.
As is often the case these days with laptops I also have two video cards, the "integrated" video card and a high performance video card.
My guess is that for some reason when I am not connected to my dock Mayavi is defaulting to my integrated video card. I would like to find some way to change which video card the renderer is using.
The performance drop could be due to something else, if anyone has any ideas I am open to any ideas.
