Yes, the average input lag of LightBoost is approximately half a frame on the VG278H and XL2411T, more lag for top edge and less lag for bottom edge, it averages out to half a frame lag. Some LightBoost monitors may have worse worse added input lag (especially if you use the older hack, or the Control+T hack, instead of Strobelight). However, 4ms is negligible for most players (except for pro players who keep eyes stationary on crosshairs).

That said, LightBoost eliminates motion blur so much (panning/strafes/flybys) that the faster human reaction time can massively outweigh the slight added input lag, so some people are definitely getting better scores with LightBoost (see improved Battlefield 3 statistics by some users who enable LightBoost). It is very playstyle dependant.

Also, due to the way LightBoost works, Adaptive VSYNC (via nVidia Control Panel) has a tendancy to produce very noticeably smoother LightBoost motion than VSYNC OFF, without adding the full input lag disadvantage of VSYNC ON. Adaptive VSYNC also has less input lag than triple buffering. Sometimes full VSYNC OFF negetates the LightBoost motion blur elimination slightly, so it's a personal preference whether to use Adaptive VSYNC to get the "best-of-all-worlds" CRT fluidity.

Playing World of Warcraft wouldn't benefit nearly as much, and pro players doing linear strafing while staring at crosshairs (slowly shifting faraway enemies into crosshairs while staring at crosshairs) wouldn't benefit as much from LightBoost. Now, other playstyles such as low-altitude high-speed flybys in helicoptors (Battlefield 3) benefit a lot from LightBoost. Circle strafing in Team Fortress 2, and fast characters like Scout, benefits a lot from LightBoost. So much, that, the faster human reaction times, from lack of motion blur, out-compensates the very minor average-4ms-added LightBoost input lag.
