G-Sync? Nvidia did not cheat anyone.

Not posting driver or any links here, just some thought.
The post that linked to an article from PC Perspective was locked, why?
You should always read before drawing conclusions, even if you are a Guru3D moderator. (not that I want to tell you how to do your job, just my opinion, deal with it)

On page 3 of the article they do test the back-draw of running G-Sync on a panel that has no G-Sync module attached to it's DP 2.1 circuit.
Which is quite interesting, since the driver which is a leaked development driver and not Gamenab's work (according to the site), does enable G-Sync for a few displays that shouldn't run with it.
Which the back-draws also proof, dropouts and blanking screen.
The whole reason behind this driver seems to be that Nvidia wants to release G-Sync for mobile devices without the requirement of a G-Sync module.

So to get some facts straight:
1: This is not a magical hacked driver
2: G-Sync does work on some displays even if they do not have a G-Sync module, but it has back-draw.
3. Nvidia did not cheat (points back to back-draws)
4. The only modification lays in nvlddmkm.sys, no other file.

It also seems like the panel itself needs to be able to handle dynamic refresh rates, but even then it's not ideal since it drops out of sync without a module long before a real G-Sync monitor does.

 

amd will be busy with a new g-sync vid to follow their other creepy ones no doubt.
all the bad nvidia publicity is great for us users though.
but sure amd vs nvidia is way too tiring but whatever.
and the OP was appreciated btw.
inb4 lock.

 

It is not bad publicity, since who want's to play games and get dropouts an black frames while gaming?
To my understanding, a real G-Sync monitor has a G-Sync module on it's PCB besides having a panel that can handle the dynamic refresh rates.

 

Here is such a module in form of an upgrade kit:
http://www.geforce.com/hardware/technology/g-sync/diy
You can use that for an ASUS VG248QE as example, since it has the required panel.

 

FYI you also get black flicker on some games with a real G-SYNC monitor. The low FPS flicker is unavoidable on all titles too, although its something you only ever notice somewhere like a 30fps locked loading screen (maybe this is intesified with SLI?)

 

Yes, but not to the extend as with a monitor that comes without the module, on page 3 of PC Perspectives test:

 

No im sure this is the case, just wanted to let you know it does happen on some games (uncommonly) so you just manually disable GSYNC

 

If so then that's pretty bad, since it just doesn't justify the cost of that additional module.

 

SOME games, its rare. G-SYNC is well worth the money imo

 

Just keep in mind that the warranty on the monitor is void afterwards.

 

I believe the reason the threads were closed is because the titles and/or content was misleading. This is the salient point: "As we turned the various dials within our benchmarks and games, we were quickly reminded why that extra PCB inside every G-Sync panel is more than just a marketing module."
The prior threads were trying to claim that G-Sync was fraudulent and was basically a 'DRM' hardware check for the module. What the article is saying is that certain panels can partially enable G-Sync functionality. The real deal is still significantly better.

 

Yup unless ASUS installs it for you

 

Yes, that is what I thought too.
I doubt it is good to force a none G-Sync monitor to archive this either in the long run.
Besides that, when you enable G-Sync on the graphic card with a none G-Sync monitor attached, nothing warrants that the sync is accurate, it is not the case that DP 1.2 has G-Sync build in either.

1.2a supports Vesa DisplayPort Adaptive-Sync, which is not the same as G-Sync, but works pretty much alike, AMD demonstrated it with FreeSync in 2014.

Gamenab is bit of what his self chosen name states, a nab.
He claims that Nvidia makes use of eDP with their G-Sync but completely forget the fact that both the hardware support on our graphic cards as the module used in the monitors has cost quite a bit to develop and build.

Nvidia would not have invested a lot of time and money in a proprietary if it would have worked flawless without the monitor module.

Plus that there are not any FreeSync monitors available yet, right?
Which will be the first monitors with DP 1.2a (eDP).
Some laptops to support the standard though.

It might be though, that Nvidia experiments with making their cards work with eDP (if it is archived via modification of G-Sync or comes on it's own doesn't matter), since that surely will give AMD competition.

 

This technology is an important step so let's just wait for the 2 big boys to work out all the details and tech. Speculating without released products is useless. We will eventually take this tech for granted once adoption is industry-wide.

 

I'm pretty sure he was referring to the thread I started. Where I linked PC Perspectives article on it.
Don't know why it was closed since I clearly stated "Wouldn't say it's safe to draw any conclusions yet as to why this works to begin with however". Apparently I'm "Another low post count user starting crap".

 

Laptops have dynamic refresh rates for power saving features. Nvidia just found a way to benefit that using G-Sync.

The special driver 346.87 or something was an alpha internal driver which enabled this feature. If you try gamenab's driver on some laptop displays you will be greeted with a G-Sync message, or find the original driver itself.

The second thread with the pcpr link was spot on, shouldn't have been locked.

 

Those laptop panels where it works on got eDP support, so not only dynamic refresh.
Seen quite a few ASUS ROG laptop owners using it, since ASUS uses such panels in some of their ROG series laptops.
Although, they are not supposed to run with G-Sync, the article describes that too.

Joke of today:
They could make it work if they disable G-Sync when framerate dips below 30fps and re-enable it when it goes above.
And then call it ... adaptive g-sync lol

 

Guru3D members are always so quick in leaking new drivers but not this time?

 

There is a link in one of the locked posts, in addition can find the discussed driver quickly by using a web search engine too.

 

These threads get closed because people are making accusations against Nvidia while not even knowing what G-sync actually is or does. That becomes obvious once you do a little bit of reading and research. You may in fact find in the near future that G-sync might get emulated through software but who wants more bloat. Some will some won't.

BTW if you watch the video, i can't believe inside the ASUS VG248QE is just taped down, like wtf. Sticky Tape holds a monitor together. lol.
