Yeah I've heard that the graphics are supposed to run on the hardware though,graphics card itself in other words ,so a very small hit to cpu time in theory

.Though I have heard comments to the contary ,I think that was from RattleDagger.
I'd love to be able to run SETI with the graph again without mouch of a hit to WU times

,haven't done so since v3.03 came out.Prior to v3.00 the GUI version was barely any slower than the CLI as long as the window was minimised.If I recall rightly v2.04 GUI was only about 5% slower than CLI v2.4 (equiv ti v2.04)
