Nvidia G-Sync hack - it works on every display supporting DisplayPort 1.2

Apparently G-Sync works without the G-Sync module, even in laptops supporting eDP. Have a look here:

Truth about the G-sync Marketing Module (NVIDIA using VESA Adaptive Sync Technology – Freesync)

Nvidia G-sync Hack (working on every monitor ?) DP1.2 and EDP | GAMENAB

If it's true, this is very bad for Nvidia, on top of recent GTX970 memory allocation issues.

EDIT:
So far there is just one person, who claims it worked (not including the author himself).
There is no hard evidence that this hack works.

Nothing to see here, keep on walking

 

LOOOL! Makes one wonder what exactly is that G-sync chip doing? It says it works with eDP, so that means laptop LCD's then? I'll have to give it a whirl!

 

It works in laptops because they have eDP panels supporting variable VBLANK. The requisite technology for variable refresh rates has existed on mobile devices for years, mainly as a power-saving measure. In fact, AMD's first demo of FreeSync was on an off-the-shelf laptop. Desktop monitors, however, need the G-Sync module because they have a less direct interface between GPU and LCD than laptops and no scaler exists which supports variable refresh.

Basically, this means native G-Sync on laptops is much closer than we thought. Or it's already here and Nvidia has simply been artificially limiting laptops users for over a year.

 

I gave it a try. It does not detect gSync for me. It's possible that it only works in single GPU eDP configs, or that my panel does not support it, or that it needs 900M + eDP at this moment.

 

Seems like many posters can get it to work but apparently it's going to happen.
I'd be laughing if this works on any of my screens. I'll be trying this ASAP.
I'm definitely going to be following this.

Can someone make sure they keep a copy incase it gets pulled

 

Don't worry, TBoneSan. I made sure I got everything on that site archived.

 

Champion!

I did a search from my phone, just found this reddit link with one of the first poster's claiming to be from PCPer calling them out somewhat.

http://www.reddit.com/r/nvidia/comments/2tv4s9/nvidia_gsync_hack/

Not sure how much stock I put in it yet. Need to have a better look at things once I'm in front of a computer.

UPDATE:

It's Malventano.. So there's some weight to that claim

You can read my post here.. So I don't have to update 2 threads.. Hope yet..?

Hmm, wonder if my Sager supports this (I'll try once I get it back from the RMA next Monday). Would be awesome if so.

Then again, I'm one of those weird people who locks a game to 40FPS instead of 30FPS and notices no added stutter. It looks totally smoother to me.

 

You have Optimus, it won't work. It'll work on a DP 1.2 screen most likely though, if you had one external somewhere. Not sure if Clevo ran external displays through the iGPU or not. If it does it won't work, unfortunately.

 

Well, I have a Benq GW2750 that I usually hook my laptop to. Not sure if that's D.P 1.2 though.

P.S. Why does everyone have a massive amount of Reputation/Trophy Points/Likes. I thought I was doing OK in the old system - turns out I suck.

 

We always had them, you just couldn't see because it was a bar. I really would like the bar and the titles to return. Pure points is meaningless if you don't have a scale to see it on, and you can't see peoples' rep power anymore.

 

This just goes to show you how stupid Nvidia is....

What I'm surprised at though is that AMD came out with a "competing" system instead of just calling out Nvidia on it.

I think a big problem is that there are both likes and reputation competing with each other.

 

It would be awesome to get G-Sync on notebooks, but I would wait for a little more confirmation first before downloading drivers off a shady website...

 

Jeez, why people gotta ad hominem instead of trying to prove/disprove his findings? The Internet sometimes...

 

Optimus = no go.
LVDS = no go.
3D screen = no go
eDP with SLI on AW17 clamed as a no go.
MSI GT72 TN panel clamed as a no go
Only MSI GT72 IPS and Clevo, both with 9xxM clamed to get GSYNC...

The best way for author to do would be finish "updated driver" so it would work but what-a-surprice he lost motivation in couple hours after being so ready...

The only way to finish this case is try it on MSI GT72 IPS and that would solve the problem but my post in GT72 owner's lounge was deleted.

 

mwahaha, Clevo with 900M series, no optimus and an eDP screen coming right up

 

I have no Optimus. Does it mean I can use G-sync with Alienware 18?

EDIT: Nobody from the comment field in Gamenab got it to work. Hmm

 

I was the guy that posted it working with the MSI GT72. Got many backlash because my account was just registered for 1 day.

As how crazy it may sound this G-Sync really works and the difference are really noticeable on nvidia pendulum demo. Tried it on BF4 and COD BO2 and the frames were more consistent but not smoother because of screen low 25m response time.

Though it lags like crazy on Planetary Annihilation.

I think this hack only work with laptop with LG IPS screen. I would like to see this tested on ASUS G751 laptop, I think it works there too.

 

I have

Thats cool. I have Samsung PLS and will try when I get home

BTW, when you say lag, do you mean crazy noticable stuttering? You didnt see that on BF4 and COD right? You should make a before/after video using Shadowplay

This is from your notebook right?

 

Yeah, that picture is from my notebook. I posted that on overclockers forum.

The lag as what you said is indeed stuttering like crazyon planetary annihilation.
On BF4 and COD theres no stutter, it works fine there. Though when FPS drops to 10-30, I start to get black flickering. The lower fps the more frequent it happens.
Some one said that some one reported the same thing on crysis on some forum.

Seems to work on Asus G751 980m, found it on reddit.

I suspect it's only working with LG IPS display laptop.

Tested on skyrim and it works there too, though again theres noticeable flickering when fps reach 20-30fps.

 

Interesting.

I have found information about some displays regarding the response time you mentioned :
MSI GT72 Chimei TN display: 6ms response time
MSI GT72 LG IPS display: 25ms response time
Alienware 18: Samsung PLS display: 16ms response time

 

Oh man. That pendulum demo looks so much smoother with G-Sync on vs off.

 

I'm lurking on reddit too to find working cases, and some one posted this.

I call ******** on Orbmu2k, because SOMETHING must've been changed. After installing that driver on a newly imaged MSI GE70 (first gen), it recognised it's eDP screen as being a "gsync capable" screen, where it didn't do that before. And it did enable variable refresh rate on that screen.

 

I can't seem to get the drivers to install on the m18x r2 to even try yet

 

Have you checked that the driver contains 980M ID (13D7)?
Check the inf

 

G-Sync is meant to not work at lower than 30FPS, right? That explains the flickering. The system only shows any advantage between 30-60FPS as that's the issue it was designed to solve.

 

http://techreport.com/news/27449/g-sync-monitors-flicker-in-some-games-and-here-why

 

None of any generation of MSI GE70 has a Monitor Tab in Nvidia Control panel due to Optimus so I have no idea where that guy found a Screen info as "gsync capable" in the first place. I have such GE70 BTW.

@smochi, would you let highly reputable member like me for instance to look closer to your GSYNC Feature by Teamviewer? Just manually tweak on/off those settings?
I suspect you say "No" though.

 

Would this work on the GT60 with the 3k IPS screen?

Awesome find

 

@ Marecki_clf, could you please write in the first post that for now there is just one who claims it worked (not including the author himself) please.
And that there is no hard evidence for now.

 

I have no idea what all of this stuff means but the modder of the G-sync drivers explains

http://gamenab.net/2015/01/28/infor...m-works-and-where-to-make-your-modifications/

 

No luck here, guess my NP9377sm-a doesn't have a eDP display. Are there are suitable eDP displays for this laptop?

 

You need to restart with driver signature enforcement disabled, remember? Unless you've done that and it still does not work.

The 120Hz screen has it, but the driver does not enable gSync there yet. I've tried. I'm asking him to help me out; if I get it working I will post about it here.

 

If you want you are free to look with teamviewer. I'm also getting tired of people not trusting me that it works and I understand why too of course. There really has to be more people with GT72 with ips and G751 that could test it too.

On reddit I found a guy that got it to work with Asus G751

Not sure this will really get noticed, but to my surprise it seems to work for me. I'm on a Asus G751JY, and while I don't have the equipment to give accurate data, there is a noticeable improvement when using G-Sync. No tearing or stuttering (in the pendulum demo)

 

I'm the person that Smochi linked to. Let me know if there's anything more I can do to help verify this.

 

What you see is not people not trusting you but adequate assessment of the facts. I didn't call you a lier, I just said that you are alone who got it, that MSI GE70 shouldn't show Display as Gsync Compatible and that video about ASUS G751 in nothing more but the exact same video from author of mod which is here

If you really agree to show GSYNC via Teamviewer please download Teamviewer Portable and send ID and connection password in Private Message. Do not give this info public.

 

I'm sorry I didn't mean to call you a liar. I sent you a PM with my teamviewer info.

 

Did a Clean Install using Nvidia`s own installer.
I have Alienware 18 and 970M SLI.

You have to edit inf to be able to install the driver. Also you need to disable driver signing enforcement if you have Win8.

I`m gonna try DDU and fully remove traces of previous drivers and see if that helps but Im not very hopeful.

No G-Sync



No G-sync display and no DSR either

 

OK, here is what happened.
I used Teamviewer to get connection to smochi's laptop.
1. His computer IS MSI GT72 with 980M GPU.
2. Nvidia Control Panel indeed show that his display is GSYNC Compatible. And GSYNC settings approve that.
3. Due to the way TeamViewer works I didn't see that Nvidia DEMO... however I am positive that it really works there or at least Modded driver really unlocks all or some part of Gsync Algorithm or the settings.

 

Some one els has reported it working too on G751 here http://www.overclock.net/t/1538208/nvidia-g-sync-free-on-dp-1-2-monitors/70
I'm starting to believe more that it works actually because he has a G-Sync monitor too.
I think this only works with LG display for some reason. I'm curious now if other displays also work.

 

Does not work on Alienware 18 and Samsung PLS at all.
Tried DDU and installing the driver again. Both with SLI and without SLI.

No G-sync and no DSR.

If it really works, its only on some select few displays

 

No problem, will do.

 

Does't work with Optimus.

 

Of course not. Intel doesn't support G-Sync yet AFAIK.

 

This TeamViewer session will be uploaded in 40 minutes, Youtube's processing time not included.

 

What patterns have we noticed on systems in which this works?

• 980M
• Non-Optimus
• Non-SLI
• eDP LG IPS 60Hz panel

Anything else?

So far, it seems like only the MSI GT72 and ASUS G751JY are confirmed to definitely work.

It seems the modded driver simply enables the variable VLANK feature (Adaptive-Sync) which has been part of the eDP standard from its very beginning (2009) and which was recently added to the DP 1.2a spec.

 

Yeah, looks like some displays like TN panel from GT72 need proper firmware anyway hence they don't work.

My-my, GT72 becomes even sexier machine than it was. Jee, that's the first time ever I call laptop this way so it means something.

 

It's still got a BGA turd CPU and will never be a proper gaming laptop... Also what's the great deal about GSync? Honestly, DSR looks more attractive to me then Gysnc... Couldn't care less about GSync but DSR better come to mobile ASAP..

 

DSR? dont care about that either, just get a high-res screen and ure golden

 

Hard to get a 3K/4K display on 17/18" notebooks :/
(No I dont want to use external displays)
