One legit answer from mdrejhon and all shit goes wrong lol
Owell, my 660Ti was in post today already but worked on my car all day so didn't have time to fetch it.

You didn't have to adjust your FAQ and I'm hardly a pro-gamer anymore 
If altering it, what you should say is that the "performance enhancing effect" of it depends on your playstyle, so YMMV. What is universal though, is the improvement in IQ as far as picture clarity goes; at the cost of brightness and contrast (but I think I saw that in there already).

Actually it already includes that in one of the items. What I neglected to mention a sentence is that pro gamer play styles can be completely motion blur independent.

Minor new tidbit:
The loss of brightness is universal on all LightBoost monitors.
But I've discovered that the loss of contrast is actually not universal.
By owning two different brands of LightBoost monitors that I purchased, I've noticed the contrast quality compromises of enabling LightBoost is major on one (XL2411T) and are minor on the other (VG278H)
On the VG278H (not VG248QE) if you stretch the monitor OSD Contrast to ~90%, and nVidia Control Panel Gamma to ~0.85, you pretty much get a LightBoost that looks almost identical to non-LightBoost (at reduced brightness, and original nVidia Gamma 1.0). No black/white clipping in Lagom Contrast, may need to notch the values up and down by single ticks till it hits the sweet spot. The specific games that ignores the nVidia Control Panel Gamma setting, I have to adjust the in-game Gamma/Brightness to compensate, to eliminate the gamma bleaching that LightBoost automatically uses. The monitor automatically uses a different gamma/saturation setting in LightBoost mode, but it can be "undone" on the VG278H to achieve a LightBoost contrast/saturation nearly identical to a dimmed non-LightBoost on the VG278H. The gamma bleach effect is gone, plus some have measured 900:1 contrast ratios in LightBoost, above the typical 600:1 to 750:1 reported, with only a very minor (unnoticeable) change to color temperature. Testers that calibrate such as TFTCentral and pcmonitors.info do advocate reducing OSD Contrast to get a better color temperature, less crosstalk trailing artifacts, and everything -- and this is very true -- however, if your goal is maximizing Contrast and color saturation (and accepting a few minor imperfections that are IMHO smaller than losses of contrast), there are already LightBoost monitors that preserves original contrast successfully. It's not perfectly identical, but darn near so (less than a few percent difference). I've noticed fewer LightBoost IQ complaints from VG278H users, with lots more LightBoost IQ complaints from VG248QE users. Also three different forum posters also remarked that the venerable, old VG278H outperforms the VG278HE, in less LightBoost artifacts (fewer LCD inversion artifacts -- less pixel checkerboard artifact). The XL2420T and XL2720T is reportedly able to be able to reach fairly close to its non-LightBoost states.
The same, unfortunately, cannot currently be said of cheaper LightBoost monitors (e.g. VG248QE and XL2411T) although the motion clarity on them and lack of crosstalk artifacts is superior on the VG248QE.
That's the good news -- it's technologically possible to do strobe backlights without a noticeable difference in contrast, though that is often tricky -- since the headroom at the bottom/top ends makes pixel overshoots easier to control (reduced overdrive artifacts -- reduced crosstalk between refreshes -- easier to hide pixel transitions/hide overdrive ripples completely by turning off backlight between refreshes).
I certainly can trust a good maker such as Eizo would be able to successfully figure this out -- bringing a no-compromises strobe/scanning mode to market (that at least equals or outperform LightBoost motion clarity). You might be aware of the BENQ 2006 attempts (that AMA-Z button) and other yesterday's marginal attempts at strobing only improved motion clarity by 30% (1.3x) -- while LightBoost improves motion clarity by as much as 12x (full order of magnitude during LB=10%). The TFTCentral article also covers why strobes are far more efficient now, and why this now needs to become a selling feature again -- now that the motion clarity improvements of strobing are far more significant (at a time when manufacturers have given up marketing this feature, pre-LightBoost era).

Mother of god dis Lightboost, I was expecting something very subtly or very little difference at all but my god, this is SO goooooooood.
