Try LightBoost. See Photos: 60Hz vs 120Hz vs LightBoost
.It's essentially the ultimate backight-based "overclocking" LCD panel pixel response.
LightBoost=100% uses frame visibility lengths (2.4ms = 1/400sec) identical to 400fps@400Hz
LightBoost=50% uses frame visibility lengths (1.9ms = 1/550sec) identical to 550fps@550Hz
LightBoost=10% uses frame visibility lengths (1.4ms = 1/700sec) identical to 700fps@700Hz
Strobing (flicker) is one method of reducing motion blur without raising Hz. It shortens the frames by the black frame insertion effect. LightBoost=10% uses 1.4 millisecond backlight strobe flashes per refresh (that's faster than Sony FW900 CRT phosphor, by the way!). Since 1.4ms is 1/700sec, it is like having 700Hz, with lots of black frame insertion (120 visible frames and lots of black frames in between). The LCD pixel transitions occur in total darkness between strobe flashes. The strobe flashes occur on fully refreshed frames. Your eyes are getting a series of CRT-like flickers of fully sharp refreshes. Bypassing the LCD pixel speed limitations.Links to Pages Talking about Sample-And-Hold Motion Blur

-- Michael Abrash of Valve Software explaining motion blur caused by eye tracking
(For his article, "persistence" is same thing as "sample and hold". His eye-tracking diagrams are exactly what I've often tried to explain)
-- iD Software's John Carmack YouTube QuakeCon chat about about motion blur & strobing
For the purposes of this, "persistence", "sample-and-hold", "eye tracking motion blur" are roughly equivalent, as everyone often use different terminologies to describe similar problems.

-- High Speed Video of 2007 LCD
; Observe how pixel transition time is slow it bleeds masively into next refresh.
-- High Speed Video of 2012 LCD
; Observe how pixel transition time is fast it is mostly finished before the next refresh begins. (Makes it possible to strobe between refreshes).For very pretty-looking LightBoost motion

as viewed in Chrome on a LightBoost monitor)
... Your game runs at framerate matching Hertz. 120fps@120Hz or 100fps@100Hz.
... This needs a very powerful GPU. Upgrade your GPU as necessary.
... Adjust game settings to keep framerate matching Hertz (e.g. use FXAA instead of FSAA)
... Control your stutters/tearing as much as you can. CRT clarity makes stutters easy to see.
... Synchronized motion HELPS LightBoost a lot. Use Adaptive VSYNC (less lag) or VSYNC ON (more lag)Edited by mdrejhon - 8/24/13 at 1:06am
