2D Lightboost erhöht den Input-lag minimal.
Wir reden hier von einer Erhöhung von ungefähr 4 ms, die durch die Vorteile von Lightboost bei nicht-stationären Bildern absolut vernachlässigt werden kann.
Ich zitiere hier einmal den Blurbusters Chief [in kleinerer Schriftart, um nicht allzuviel Platz einzunehmen]:
"LightBoost does increase input lag by half a frame.
Since input lag for top edge of screen can vary from bottom edge, and strobe backlights give interesting behaviors — For the average ASUS/BENQ 120Hz LightBoost screen, non-LightBoost TOP/CENTER/BOTTOM is 3ms/7ms/11ms while LightBoost TOP/CENTER/BOTTOM is 11ms/11ms/11ms. This averages out to half a frame added input lag (3ms -> 7ms) with LightBoost.
HOWEVER… The elimination of motion blur actually can improve human reaction times in situations where you are tracking eyes on moving objects all over the screen. The lack of motion blur reduces human reaction time significantly enough to more than outweigh the extra input latency, especially for FPS gaming and many others. Check out the improved BattleField 3 scores with LightBoost as an example as how increased input lag doesn’t necessarily mean worse scores. Unless you play in a very bright room at daytime, the loss of brightness will hurt your game more. Players that stare stationary only at crosshairs at all times even during strafing/turning (no eye movements away from crosshairs), will not benefit much (if any) from LightBoost. But if you track your eyes (e.g. Blur Busters UFO Motion Tests when turning ON/OFF LightBoost), eye tracking creates display motion blur that makes it harder to track moving objects, slowing down your reaction time for these situations. The question is very person specific: Deciding if LightBoost benefits outweigh the very tiny input lag it adds (half a frame – 4ms). It definitely does for many people, but not necessarily for everyone and every game. For example, it will benefit fast FPS far more than, say, World of Warcraft.
And obviously, your game needs to run at triple-digit frame rates in order to really benefit from strobe backlights (because you want framerate matching stroberate for maximum motion quality). If you are running at slow frame rates such as 30fps or 60fps, you won’t really see the benefits of LightBoost, and will prefer to disable the strobing. You won’t get the similar TestUFO benefits in your game in that case. However, when the game run at consistent 120fps, and you’re using a really good and smooth gaming mouse (mouse movement becomes as smooth as keyboard strafing movements), the clarity improvement become massive (similar to TestUFO)."
