Hi Thorsten,
the problem which you experience is because of lacking direct memory mapping between
OpenGL and CUDA memory. Even if CUDA (at least it was in version 2 so) supports
GPU<->GPU memory mapping, whenever you access to OpenGL textures there is a
full memory copy performed.
I am not aware if this was solved in CUDA3, maybe you should check it out.
CUDA2 definitively doesn't perform direct mapping between GL textures and CUDA
textures/arrays.

I know that OpenCL 1.1 added a bunch of OpenGL interoperability features
(clCreateFromGLBuffer(), clCreateFromGLTexture2D(), etc.), and I thought
I heard that the newer versions of CUDA supported similar features.
OpenGL 4.1 added some CL interop features, too.
