Sorry, but it does not do anything for flashers, only GI. I don't know about TSPP in particular, but I designed it to allow the GI to ramp on and off when the relay is turned on and off. Some games do this rapidly, causing a distracting flashing GI.

With default settings it's about 50 ms per step if you're going from off to on or vice versa. I have had my wife install a non-ghosting bulb in one location and a standard bulb in another, and I was able to identify them by sight, through an insert. I would guess that I'm pickier than most people, though.

In a couple of cases, like Spider-Man, there are bulbs that stay lit at a dimmed value, and with those it prevents you from being able to use those low brightness values. A dimly lit bulb won't look dim in that case because the lowest you'd be able to set it would be 40% or you'd see flicker any time the game used the dim lighting.
