NO. Do not use any graphical screen savers with SETI because it will slow down or even stop SETI. SETI is designed to run in the unused cycles of your PC's CPU so how can it run if your pretty screen saver is using all or most of those cycles? It can't or if it does it will be very slow. It may double or triple your times per Work Unit.
Any Visual Screen Savers that render 3D, render Ray Traced graphics, or create/display slide shows of large graphic images will just about kill SETI. SETI will wait for the CPU to become free and since the highly Visual Screen Saver is so CPU and memory intensive, SETI just sits there and grabs what little it can.
Moral. Use nothing but blank screen (or none) if you want SETI to crunch normally. Set your power saving features to turn off the Monitor after 10 to 30 minutes and or just turn off your monitor at night. Make sure to only use "None" or "Blank Screen" as your Screen Saver setting or your SETI WU (Work Unit) times will greatly increase.
