Thanks for the response. Just to clarify - I have the data model of the buffered image, manipulating it is not the issue.  The issue is copying this data to the screen.  

Looking at GLJPanel it looks like it might use pixel buffers, but I have heard that they are deprecated.  It does sound like the right thing though.  I could setup an FBO but not sure that would really be faster - manually drawing 2048x2048 pixels into an FBO through a pixel shader sounds slow to me!

If Sven is available to give some insight that would be great. Thanks!
