My flags are:
-v -w128 -f200
-v to enable vector support
-w128 has something to do with optimization.
-f200 is the secret for smoothness. It limits the frames (or framerate?) to something rather. It doesn't seem to affect the hashrate in idle!
I don't even notice that GUIminer is on while watching vids and doing desktop stuff. Just awesome!

I set the CPU affinity to my last cpu-core only, since that's the one that is the least used by non-multithreaded applications.
