Is this on a Vista/7/8 machine? On these a pure device may be disabled - see: <a data-cke-saved-href="" href="" "="">http://msdn.microsof...4(v=vs.85).aspxThis is it. Thank you very much for this link, I didn't know this.
When the fixed-function vertex or pixel shader converter is used, the pure device is disabled. When an application requests the pure device, the Direct3D runtime creates a HAL device.
And thank you all guys
