I have a question about performance on the RT.
I have VS2012 running on Win8 Pro on my brand new Alienware M14X, and I don't have any issues running the Marble Maze sample on this laptop.
However, when I deploy Marble Maze to my SurfaceRT, the performance is unbearably slow after I get past "Start Game". Moving the marble by tilting the tablet is painfully slow, and the game is essentially unplayable.
Note that I can run Windows Store apps on my SurfaceRT without issues, and I can also deploy and run my own apps to the device, that I built from online tutorials (C#/XAML photo picker app and C++/DirectX first-person shooter sample).
Do you have any thoughts on this?
