I want to run my DX11 app with PIX attached.
But the SDK samples that use DX11 fail to start from PIX. They do run as standalone .exe's or from Visual Studio 2010.
So far I've tried samples: SimpleSample11, OIT11, DynamicShaderLinkageFX11, PNTriangles

I have had better luck with DX10 and Tutorial4, PIX is able to do a single frame capture and the interface switches over to view the results.

Working with 64 bits PIX, the latest DirectX SDK, June 2010 on Windows 7 64 bits, new laptop with NVIDIA GeForce 670M. Beginning to think it's the video driver, I had different errors before I updated to NVIDIA driver 304.79 beta. Going to try with a desktop PC tomorrow.

PIX reports it fails to create a D3D11 device,
Frame 000001 ........PRE: D3D11CreateDevice(0x000000000042E430, D3D_DRIVER_TYPE_UNKNOWN, NULL, 2, 0x0000000004CEF704, 1, 7, 0x000000000019F098, 0x000000000019F0D4, 0x000000000019F0B8)
An unhandled exception occurred.

Thanks for any suggestions

I'm having better luck with 32 bit builds of the samples, PIX is collecting and showing results from SimpleSample11, SimpleBezier11, PNTriangles11, and DetailTesselation11.
On google, found someone else had issues with 64 bit builds.
Is this a known issue?

I haven't had any problems with x64 apps, and the samples seem to work fine for me in PIX. So it must be something with your setup in particular.

This might be a really weird suggestion, but in the nVida control panel, try setting your power management mode to "Prefer maximum performance" (it forces the card to run all full perf all the time), this setting was giving me quite a few issues on my GT555M with DX11 apps when in adaptive mode (be warned, it'll probably make your battery sap way faster in normal windows, I turn up to perf mode only for DX11 games and dev, oh, and with more power comes more heat when idling, so keep it well ventilated).
