I've run SimpleGL example from NVidia GPU SDK, it works fine. I've made some investigations on it and found that in SimpleGL wglGetCurrentContext returns 0x10000, however in python applications it is permanently 0x20000 (I'm using pygame to create opengl window). I've tried to substitute GL_CONTEXT_KHR value in context properties with 0x10000 but with no success. Here is list of properties I'm passing to Context creation: [(8200, 131072), (8203, 18446744072820433310L), (4228, <pyopencl.Platform 'NVIDIA CUDA' at 0x67c1390>)] > Thanks, > Andreas > > > >
