Yes -- small tearing formerly hidden by motion blur will become easier to see.
You need to tweak that a bit, such as enable VSYNC, triple buffering, or alternatively raise your frame limit (crazy high fps_max in Source Games, even try fps_max 240 or 480), and use a more powerful GPU, and lower your detail level. Doing high fps_max+powerful GPU will reduce tearing if you prefer VSYNC OFF. Once your GPU is generating frames far beyond 120fps, the high fps_max turns fewer bigger tears into many smaller tears, which will be harder to see.

So for source engine that's the benefit of fps_max 240 (or higher) instead of fps_max 120 -- less noticeable tearing because of smaller pixel shifts along each tear... (two small hard-to-see tears per refresh rather than one big easy-to-see tear per refresh) .... but your GPU needs to be crazy powerful to shoot well past 120fps.

Also, the LightBoost effect is only really worth it when you can push the game all the way to 120fps@120Hz, so don't bother with LightBoost if your GPU isn't capable of 120fps. But when it clicks, everything is crystal sharp & you can identify enemies without stopping moving, allowing faster reaction times. Of course, LightBoost can also benefit other things like browser smooth scrolling (Chromium Smooth Scroll extension for Chrome).

On my monitor, LightBoost works at 100fps@100Hz, so if you're having problems hitting 120fps@120Hz, try setting the refresh to the 100Hz preset in Control Panel. (Custom Resolutions does not work with LightBoost, and refresh rates under 100 does not work with LightBoost)

And yes, the color/brightness does degrade when you enable LightBoost especially on ASUS. Raise your Contrast to 92 (that adjustment is still accessible via your monitor), it looks a lot better. I am able to improve the color a little bit through the nVidia Control Panel, though it may lead to some color clipping or blowing out highlights. I'm anxiously awaiting Vega's Benq XL2411T review, since Benq's are reported to be much brighter LightBoost monitors. I expect future strobe backlights should become better and better over the long term, with better panels and better LED's.

Long term, we need an easy utility button to turn on/off LightBoost on demand, so we can enable it only when we want it (e.g. FPS).

Just upped the contrast from 60 to 80 and yeah massive difference. Have it right down to 60 for 3d as there is pretty much no ghosting. So when I first tested this I would have been seeing much darker results that someone with their monitors on default settings. I'll give it another go over the weekend.

What kind of monitor and GPU setup do you have?

I have been reading about PixPerAn and going to test it out with the Light boost hack. I'll post back my results.

Remember also that if you need 120+ FPS to match the Hz, that some graphics settings stress the CPU more than the GPU. In a lot of games, you need a fast CPU just as much as a fast GPU in order to feed frames that fast. Basically for this you just need a fast computer overall unless all you play is CS 1.6 or something. biggrin.gif

Pixel Persistence Analyzer (PixPerAn) Readability Test Results 120hz: Wow just wow! Speechless.........

-Highest readable tempo without Lightboost (LB) was 7 and even that was blurry and my eyes where straining to read it.

-Highest readable tempo with Lightboost was 30 (Only could read the first 5 letters)

So when i first turned on LB and tried the last failed tempo of 8 again (which was blurry non-sense w/o LB)and was shocked how crystal clear it was. Kept going up until i reached tempo 24 and completed the test successfully. But at this crazy fast tempo my head was hurting at all the right to left motion that my head was doing to keep up with this speed. Next I turned it up to the insane tempo of 30. The speed is so fast my eyes have trouble keeping up with the letters, but when i finally train my eyes to lock on the letters THEY WERE CLEAR! I could only get the first 5 letter out and correct, due to the insane speed of tempo 30. Maybe a trained eye like Vega can get out all the letters, but for me to be able to read 5 letters states that yes this LB hack makes my VG278H monitors have Zero perceivable motion blur.

Anyone that has done the hack must download to see the results. http://www.softpedia.com/get/Desktop-Enhancements/Other-Desktop-Enhancements/PixPerAn.shtml

On one side note there was a minimal ghosting effect with the letters. Similar to the 3d ghosting effect. The test letters are black print, the test background is white, and the ghost behind it was a very light grey/white. The ghosting was not a blur or trailing effect it was a perfect letter, just extremely light and very hard to see. The only ghost letter that was visible was the last in the grouping as im guessing the others ghost into the other black letters. But in no way did the ghosting effect the readability of the extremely fast moving letters.

I disagree, but I don't mind trading graphically fidelity for frame rate.  

 

Things like AA, post processing.. etc.. just add latency.  The only thing I really keep on high is textures :o

I have the Benq XL2420T and no 3D glasses i was wondering how i install the tweak req file for accessing lightboost without 3D glasses. The link doesen't download anything it just shows the correct values, and do you guys think SLI 560 ti is enough to make lightboost worth it?
All help appreciated smile.gif

What is there to disagree with? There are some games out there that even with my 5 GHz IB the frame-rate won't always stay at 120+ with graphics settings set minimum and showing low GPU usage. This means the game is stressing the CPU more and is CPU limited. A recent example of this is Darkfall: Unholy Wars beta.
