CUDA GL Interop

In my graphics application I’m doing some computations with CUDA and afterwards I visualize
the image via OpenGL.

By now, I use cudaGLMapBufferObject/cudaGLUnmapBufferObject. The well known
problem is the performance. 1440x900xfloat4 => 14ms on a GT330M.

I realized that the calls cudaGLMapBufferObject/cudaGLUnmapBufferObject are deprecated.
Can anyone tell me if the new way of doing it (cudaGraphicsResource) increases the performance?

Thanks in advance.
