Hiya, I've just downloaded the latest DirectX SDK and tried to run some of the D3D10 samples. I've run the provided binary copies, and also compiled them myself, but I'm getting a strange error. Would anyone be able to help? The DXUT framework seems to try to create a D3D 10.1 device first, and then D3D 10 if that fails. When it calls D3D10CreateDevice1() though, I get an unhandled exception. My graphics card doesn't only supports up to D3D10, and the samples work if I force it to try this first instead of 10.1. The strange thing is that looking at the call stack, the exception is being thrown from a frame called 'nvwgf2um.dll' - which looks like an nVidia file/driver of some type. I was wondering if this is a common/known problem to anyone? If not, I'll have to try and report a driver bug somehow... Thanks for any help! [smile]

Well D3D10CreateDevice1 is used in dx 10.1 and if that file is a part of nVidia drivers I presume you have a geforce graphics card, which doesn't support dx10.1 so you must you D3D10CreateDevice()

Thanks for your reply. I do have an Nvidia card.

You can create a basic D3D 10 device with D3D10CreateDevice1() though, by passing D3D10_FEATURE_LEVEL_10_0 as the feature level. Surely the function should return a failure code if 10.1 isn't available, rather than crashing the driver?

That's how I would have done it as well - but DXUT calls the 10.1 function, without regard to whether it's creating a 10 or 10.1 device...

Thanks again.
