Hello all,
My current machine has both an NVIDIA and an Intel GPU. When the Intel is set as primary, all CUDA/D3D interop fails mysteriously (unknown errors / errors that aren’t even supposed to be returned). I tried both the D3D9 and D3D11 interop samples directly from NVIDIA’s site as well as my own code. However, if I set the NVIDIA-driven display as primary, then everything works fine.
The same problem was reported by a user on Stackoverflow.com: http://stackoverflow.com/questions/16157749/cuda-unable-to-register-direct3d-resource
My OS is Windows 8 Enterprise 64-bit and I am running the latest drivers from both Intel and NVIDIA.
Is this a known issue?
