Hi Erwan, You don't provide enough information about your setup for us to guess what might be wrong. How are you setting up your scene + viewer to render to the image? Is your rendering just for the purpose of generating an osg::Image as output? How you are testing the results of the image? What threading model have you used?
As a general note, can you do the processing in shaders instead on the CPU? Avoiding the readback from the GPU to main memory can be a big save in performance. Robert.
