*compares 2 different monitors* Oh that's different

[spintesttech]

Bro ghosting comes from the monitor not the Graphic cards, so you should change the monitors

[Buffinator]

Provided the monitors are decent. There's NO discernable difference between gsync and free sync when configured correctly. Decent free sync monitors have LFC. And blur is caused by pixel response time not as some artifact of sync technology so entirely panel dependent.

[Xikiruen]

Freesync now refreshes the panel twice when the frames drops under 50 (in this case) so if the graphics card delivers 40 the panel will run at 80 so no screen tearing even at low fps

[AS-gbwz]

What?
Freesync also have feature for eliminating tearing below the freesync window called the Low Framerate Compensation.

[dragopac]

I think it would have been better if you used 2 exact same quality monitor. Half of the comments during the video was around ghosting more apparent on the freesync monitor. This is why we need to check response time, hz and input lag when looking to buy a new monitor....

Sorry for my bad english!!

[pedjakrcedinac]

You wouldn't have screen tearing below 50 fps on free-sync, because you have LFC. Also, capping FPS at 142 is probably not low enough for free-sync as frames will spike above 144. Not sure if you are using in-game frame-cap or riva-tuner, but either way neither is accurate

[jordanmackay]

Cheap Korean budget Freesync monitor vs Dell G-sync monitor and your surprised there is ghosting? Come on your better than this.

[gerarddeboer]

This comparison makes absolutely no sense... you should have bought two of the same monitors but one specifically made for g-sync and the other for FreeSync. MSI, for example, has many sets of those... very flawed comparison. By the way, ghosting doesn't have to do with sync technology, but with the screens' ability to refresh its pixels lmao

[justspaztik]

You forgot about LFC on FreeSync with AMD. The monitor can go below the freesync range, because then it just doubles frames up. Say you drop to 40fps, it will change the monitor to 80hz and show each frame twice. Also, did you cap the frame rate as to make sure you're not going over the max refresh?

[salemgiath]

Dude no offense, I love your videos and all.

But if you don’t have the budget for a proper comparison video, don’t make one.

This video was so scuffed and should’ve never been uploaded..

[zergtoss]

Man one thing about these tests is even same model monitors can vary lol

[RuthlessFares]

I've actually found freesync to work better than the g-sync one i bought, both on the same system with nvidia gpu. That's comparing explicitly tearing and sync properties, not quality of panels. 34gk950f, freaking amazing monitor: 3440x1440, 144hz, "HDR", freesync. Make sure it's the freesync version, up to 144hz vs 120hz on the gsync model. Also, freesync works amazing with nvidia gpus. The freesync blew the water out of the PG348q g-sync

[AlexLionson]

It's a panel refresh rate difference and not adaptive sync implementation. But yes, if the price difference is small in this case you can for for g-sync one because it has better panel.

[northwood]

I use the Free-sync version of the 21:9 Predator X34 (bought it a few years back thinking AMD would put out a card to compete with Nvidia in the upper range; not knowing Nvidia would open up G-sync before that to save about $340 over the G-sync version at the time. Even though this panel isn't "certified" it has made a world of difference and the range is really good (40-75fps at 3440x1440).

No it is *NOT* "better".
Freesync and G-sync each have different advantages and disadvantages *other* then just cost, I'm talking features here.
What you can say is that certain *implementations* of G-sync is better then certain *implementations* of freesync.
But G-sync is really just ahead when Nvidia has released a new G-sync module lately.
They don't always do so though.
And when it's been a while since last time the other scaler manufacturers catch up in freesync features and even passes the G-sync module in a lot of ways.
Advantages are often things like slightly lower latency (except when Nvidia has recently played catch up), more connectivity (except when Nvidia has recently played catch up) and so one and so forth.


As for the monitors that objectively give you a worse experience then G-sync those are so cheap that they're not *competing* with G-sync at all but with the monitors with *no* adaptive sync at all.
And a *bad* freesync implementation is still superior to no adaptive sync even if it might not be on par with a good freesync or g-sync implementation.


Anyway, remember that there are multiple scaler manufacturers that provides freesync support in their modules, and some of them are on par with G-sync already and others haven't quite figured out this whole adaptive sync thing yet and are miles behind G-sync, and some are occasionally ahead of G-sync (although Nvidia has done a good job of never allowing them to stay ahead for long).

That has *nothing* to do with what is "better" or not.
What you're describing is the qualification standard.
That is what Freesync 2 offers if you care about that kind of stuff.
As well as LFC support for Freesync 1 monitors.
It's as simple as going to AMDs website and looking up "LFC" in the list of compatible monitors.
Monitors *without* LFC are not competing with G-sync monitors at all, they're all either competing with no-adaptive sync monitors (and are therefore way, way cheaper and *intentionally* using a worse and therefore cheaper implementation of freesync) or they're resolutions and aspect ratios that G-sync don't offer.
Either way the scaler manufacturers are trying to find ways to differentiate themselves and to be competitive with Nvidias scaler.


This isn't some kind of one sided this is *always* better then the alternatives issue.
Realtek scalers have *some* advantages and some *disadvantages* vs Nvidias G-sync depending on the particular products you're comparing.
MStar scalers has certain *other* advantages then either of the other two and also disadvantages.
Same with Novatek scalers.
This is engineering we're talking about here.
And engineering *always* involves trade offs.
And here each of them (Nvidia, Realtek, Novatek and MStar) brings different things to the table for the monitor manufacturers to take into consideration and in many cases you'll get a *better* experience with the Freesync alternatives as a end user.


Yet you claim that Freesync is somehow inferior because AMD *deliberately* gave people the choice to buy cheaper implementations that does not fulfill any standards like LFC support or Freesync 2?
Like seriously?


We're computer enthusiast here.
Anyone who don't know what LFC support is or Freesync 2 is probably don't know what adaptive sync is to start with making this point moth or are just bad at researching computer parts and buy prebuilt.
Or they're Nvidia shills who don't *care* about researching AMD stuff.
As for recommendations to newbies building computers just tell them to buy Freesync 2 or Freesync 1 with LFC support and *not* without if they're sensitive to tearing.
Or tell them to buy freesync and save them some money without having to argue with them about why this "freesync" thing is actually worth spending money on vs a monitor without any kind of adaptive sync at all since they quite frankly probably don't even know what tearing *is* at that point...

[jkdYann]

you forgot enhanced sync, it does also help against screen tearing

[polidoumhd]

2 different panels... ofc he will say the brightness is higher or something else bc of the different monitors

[CitizenTechTalk]

You should have used two of the same brand and model monitors (not literally obviously). One with G-sync and one with Free sync (proper compatible one).

That way quality of panel as you said would then offer a more comparable experience yeah?

[dimintordevil]

dude, if you get ghosting, then the monitor actually can not process 144hz because of grey to grey (thingy ). you should try locking your frames a little bit lower . in most cases, monitors advertised as 144hz can only display something like 120hz . so if you lock your fps even lower, like 110 or maybe 100 or 90, you might not get ghosting . Besides, does the ghosting appear only when you turn on freesync at 133 fps or not ? you need to test more . this video does not provide enough info
