Your first D3D11 app and you went straight for tesselation. Well, if that isn't bold.
As mentioned, PIX isn't of much use here. Well, it doesn't crash, but e.g. you can't debug these shaders.
I've never actually been able to get PIX to debug any shader even in the dx9 days. It always had crazy bugs that changed after every update. Still, it was useful just to see what the vertex streams were composed of. I'm quite sure that my vertex buffers aren't how I am imagining they ought to be. Staring at my code and waiting for an epiphany is discouraging, but I already found a couple of bugs that way.
I'm frustrated because PIX currently ends my computer session without any kind of error message, and without PIX my CPU code steps through fine and each frame appears to make it to the draw call. BTW I am also using C# with SharpDX.
