Had my first taste of it too, and hated it. The lag was insane, even with my graphics turned way down, and I have a pretty good set-up. What really bothered me was the bouncing around. Combine that with the noise (headphones) and the flashing colors from powers, and I actually started to feel sick. I'm not prone to seizures, but seriously, if the sonics had to be toned down because it was bothering people, this may send many over the edge. Fortunately, it is optional. An option I don't intend to use often.
