so would this benefit systems with 120Hz monitors running at 50-60FPS in game?

Thanks! smile.gif

No it won't. It needs 100+ fps at 100Hz or 120+ fps at 120Hz.

Is this really needed? for a new monitor out of the box that never had LB enabled


If you don’t have a 3D emitter, use the “Edit…” button at the very top to set the product ID to ACI27F8 for each monitor. This will make the driver think you have a VG278H with a built-in emitter so you can enable 3D mode. The model name doesn’t matter and can be set to whatever you want. ?

And these 2 arent needed if you had LB enabled before right and you done a fresh OS install

In the NVIDIA control panel, open the “Set up stereoscopic 3D” page, then click the “Run Setup Wizard” button. If the button isn’t there, uncheck “Enable stereoscopic 3D” and click the “Apply” button.

In the setup wizard, click the “Next” button, then click “Next” again. At this point, it should enable LightBoost, and if you don’t have an emitter, the mouse cursor will be very sluggish and jerky. If you don’t need to enable 3D, you can exit here. Otherwise, continue the wizard as usual.

It looks better at 100+FPS at 120hz, but it's necessary per se. I'd say minimum 60 frames otherwise it looks all juddery.

Will this apply to Skyrim running with vsync at 60fps? I know the video shows skyrim running at 120fps but that supposedly will break physics in the game as well as all game time-based events.

Had to reposition my system in other room so taking the power cable off removed LB as well, I'm on 144Hz non LB now after using LB for "quite" long, Wow... and thinking I had a 60Hz T240 Samsung before.. It looks so bad compare to LB thats its unbelievable, don't even care about gaming. just browsing text gives me a headache already cause you're so used to zero motion blur redface.gif gonna enable LB back right now!

What's the compatibility with Lightboost? I'm looking to get an old Nvidia card just to enable Lightboost then switch to my 7970.

If you use lightboost 120hz and run at only 60 you will suffer ghosting or double image. Best to get as close to 120fps as possible in lightboost 120hz. It's the reason why someone should find a way to make 60fps at 120hz lightboost work without double image.

You need fps=Hz for maximum LightBoost benefits.

Otherwise, the repeated refreshes ends up contributing to sample-and-hold motion blur (double image effects, stutters, increased motion blur, etc). The stroboscopic backlight is enabled only at certain refresh rates (e.g. 100 Hz or 120 Hz), and you need fps=Hz for best motion on stroboscopic displays (CRT, LightBoost). LightBoost and other stroboscopic backlights doesn't look awful at just 60fps, just that most benefits disappear if your strobes aren't synchronized with framerate (which requires frame rate equalling refresh rate).

So you definitely do need 120fps @ 120Hz -- preferably 100fps
Which you can easily do on most systems with a just a high-500 or 600 series GTX if you just run older games (Source engine games). However, to get even just 100fps in games like Crysis 3, you need a Geforce Titan to pull that off. Games like Quake Live, Counterstrike and Team Fortress 2 have no problem attaining 120fps; those games are still fairly popular.

P.S. New Samsung tip. Better colors during stroboscopic mode; change Samsung OSD setting “Magic Angle” to “Group View”

This can be accomplished by software-based black frame insertion, there's a special modification to MAME emulator that allows the 60Hz LightBoost effect by blacking-out every other refresh:
www.blurbusters.com/mame

Theoretically, it can be implemented as a system-wide software-based black frame insertion driver, that can produce the complete LightBoost effect at 60fps (with the attendant 60Hz flicker and further reduced brightness, as a compromise). This works around the hardware LightBoost limitation of being restricted to 100-120Hz.

Welcome to the LightBoost experience.
I also did a resolution downgrade (from 1200p) to get the motion clarity upgrade.
