Cant get this to work with quakelive but works with black ops 2 and bf3... Also massive stuttering and frame drops when first loading game but is gone after around 30 seconds.

Awesome! Thanks for the great guide Mark thumb.gif

After I tried out your 2d Lightboost I refuse to game on 2d without it!

Was just about to get a 27" IPS 1440p screen next to me 120 hz TN. Gonna run my TN in 60 hz mode for a while to see if I can stand it.

Regarding the lightboost 2D motion blur reduction. I feel like waiting untill companies like Asus, Benq or even Nvidia exploit this new feature for 2D gaming instead of being a "hack" like now.

Also I would assume even 60 FPS 120 HZ this would have a great affect right ?

From what i have read no. You need close to 120fps @ 120hz to get the full 2d Lightboost effect. But i have had a couple games where 80fps looks stunningly smooth, and others where 80fps looks like crap.

It depends on the game and how smooth the 60fps is. If it's smooth 60fps without random frame fluctuations.

The motion blur on LCD's had a double-edged-sword advantage: Slow LCD pixel response hid stutters better.
Stutter drops on CRT's have always been more noticeable than stutters on LCD's.
LightBoost strobe backlight displays produce this exact same motion behavior as CRT.
People who have tried CRT 30fps@60Hz versus CRT 60fps@60fps, will tell you that framerates locked to refresh rate, looks so much better.   The same thing happens with a strobe backlight.

So to not worry about stutters, you should have really high framerates.
Ideally, 120fps@120Hz, but many framerates such as 80fps and 100fps will still look better as long it output the frames "consistently".
For 100% full benefit of LightBoost, you really want the full framerate matching refresh rate.
At 120fps@120Hz, you will be buttery-smooth, zero motion blur -- far smoother than non-LightBoost 120Hz.
Also, LightBoost supports 100Hz, so you can run 100fps@100Hz, if necessary.

Try installing the ForceLightBoostWithoutGlasses.reg file, so you enable LightBoost at the Windows Desktop. Games that run inside a web browser, will more frequently require this registry tweak.

Good news! I found vendor-supported instructions!
No registry tweak or INF files! But the vendor supported method requires you to have the 3D emitter, and you don't get the LightBoost effect at the Windows desktop but in games instead.

LightBoost HOWTO: Zero Motion Blur on All LightBoost LCD's:
--> www.scanningbacklight.com/lightboost-zero-motion-blur

- Two separate sets of instructions included.
- Vendor supported method (no registry/INF tweaks, requires you to buy 3D emitter even if you don't use 3D)
- Hack method (bypass 3D emitter, no need to purchase)

Mark I have found a couple flaws using that method.
1. There is a performance decrease in some games with 3d enabled & Ctl T vs 3d disabled 2d Lightboost. I don't have exact figures, will have to test more.

2. With BF3 multiplayer (which many people will use this for) Ctl T 3d re-enables itself after every death. So 3d will be constantly on and off.

Does the performance decrease occur in all games, or only some games?

Only tested in BF3 and it was a few Nvidia drivers back. I will test with newest drivers and report back.

Ok it wasnt as much as a difference as i remember with older drivers. It is still @ 4-5%, but i guess that is within the margin of error. But i did still have the continuous switching back and forth of 3d with Clt T method.

Tested with same empty BF3 mp map @ 5910x1080 bezel corrected res.
3-way SLI with 4th card dedicated to PhysX

Ctl T Method



3d disabled in Nvidia Control Panel, LB enabled
