The G-Sync on FreeSync Thread

[WYP]

Nvidia has now enabled support for VESA Adaptive Sync within their Geforce Drivers. Link Below.

https://www.overclock3d.net/news/gp..._to_enable_g-sync_on_adaptive_sync_monitors/1

Since Adaptive-Sync is now a thing on Geforce cards, I thought it would be nice to have a thread where we can discuss how well it works, as there should be some people here with FreeSync monitors and Geforce graphics cards.

If you give it a try over the next few days please post your monitor name, how well it worked with G-Sync and what GPU you are using. This should help provide some useful data for other forum users.

Thanks.


The Monitor List

- ASUS MG279 IPS 1440p 144Hz - RTX 2070 - VRR Range 35-90Hz - Over MiniDisplayPort - Flickering Issues - Reported by Dark NighT

- Iiyama Prolite B2783QSU 1440p IPS - GTX 1080 - VRR Range 48-70Hz - Over DisplayPort - No Issues So Far - Reported by Tolemac

Great idea for a thread Mark!

 

[Dark NighT]

I will download these now and see how my monitor works with it for a while and report back.

Are NVidia not releasing any of the data from the 400 other monitors they tested? I guess that's quite optimistic for prospective users, if they were all truly failures like the couple of examples they gave us I think we'd have known about it by now.

I'd imagine that a large portion of the list requires no testing, as any FreeSync/Adaptive Sync monitor that has a low VRR range will automatically fail, such as the 40-75Hz monitors etc.

That would create a large list of failures in itself, never mind the early FreeSync panels that have overdrive issues.

 

[Dark NighT]

Alright, that did not take long for me to test.


Monitor is a Asus MG279 IPS 144hz 2560x1440 monitor that has a freesync range of 35 to 90 fps, it is 3 years old.

The Gpu i am using is a Msi RTX 2070 Armor, connected with displayport to mini display input on the monitor.


Results then, ive set the gsync settings to just fullscreen mode, and then later the fullscreen and windowed mode and in both settings across most games i quickly fired up it didnt sync a thing, it just went straight to going many more fps then 90.


On the one game where it kinda attempted to work, Guild Wars 2 and it produced this.

Looking at this, it looks like my Monitor isnt having any of it, which is fine because 144hz is better then 90 anyway and i was not expecting much anyway because of it.


It could be that another video card, or even cable could make a difference, but i think in general this monitor is not suited for it.

Really? There are G-Sync monitors that also have a 35Hz range, and lower than 75Hz max rates, so that would be kinda devious of them. Also many seemingly perfect & well reviewed monitors with much larger ranges seem to have failed.

Also, their wording was specifically "tested", as opposed to just certified(You'd think the hundreds of other AdaptiveSync-supporting monitors & TVs beyond the 400 they claimed to have tested would be the automatically rejected ones but who knows), and that testing process is apparently on going.

Nvidia hasn't specified how they "tested" or what their exact criteria are, but as far as I am aware all of Nvidia's G-Sync monitors support a range from 30(or less)-max refresh, basically using a standard similar to AMD's Low Framerate compensation (LFR) or by offering that range naturally.

I'm not saying that they did no testing, I'm just saying that you could easily find a few hundred sub-par FreeSync/Adaptive Sync displays that you know will fail on test one and are, therefore, "tested".

If Nvidia really wanted to be consumer friendly they would publish their list of tested displays and detail the exact problems each monitor had.

Let's say I bought a top spec FreeSync monitor which is likely to be GSync compatible.

I now don't know what the advantages are to buying a G-Sync monitor are? Nvidia haven't been particularly clear on this don't you think?

It says it enables the VRR elements of G-Sync but isn't that all G-Sync was anyway?

 

[looz]

I guess the point of G-Sync is being a "premium" product which has HDR and is guaranteed to work as intended.
So basically if you can be bothered to do your own research, FreeSync 2 is the way to go.

All G-Sync displays were certified to offer "high-quality VRR", so it needs to meet other specific standards for input latency and meet Nvidia's overdrive specs (no ghosting etc).

A good FreeSync gaming display should do pretty well in these regards, but unless it is Nvidia certified there are no guarantees.

 

[grec]

According to NVidia G-Sync monitors are better than "G-Sync Compatible" adaptive sync monitors because... they do some more image/colour tests on them.
G-Sync's brand mostly lives on for G-Sync HDR, which still competes with FreeSync2.

FreeSync2 isn't supported or expected to be supported on NVidia cards is it? This is just VESA AdaptiveSync support, FS2 is a lot more than that(The whole encoding/decoding pipeline changes in an FS2 monitor).

 

[looz]

Oh, I wasn't aware of that. I was in the belief that FS2 is just a more strict standard for AdaptiveSync monitors, like G-Sync compatible.

 

[NeverBackDown]

It is. Has higer requirements for HDR and color reproduction and brightness. The VRR part just means it supports LFC.

Mark, would it be an idea to update the original post with reports from users?

https://www.techspot.com/article/1630-freesync-2-explained/

If you buy a FreeSync2 monitor today then yeah that's essentially what you're getting because nothing really uses/supports the FreeSync2 software stack(It requires application specific support for syncing tone mapping and the like with the display in one step), but FreeSync2 in itself is basically an AMD specific software stack to allow the GPU to communicate a few things to the display(To save things from having to be done twice and make sure they're done correctly).

AMDs validation is roughly equivalent to the new DisplayHDR500 certification spec though if you wanted a non-FreeSync2 AdaptiveSync HDR monitor for your NVidia GPU.

Seems to be working fine on my iiyama Prolite B2783QSU freesync monitor I have only tried sniper elite 4 but will test it in more games when I get the time Graphics card is a GTX1080

That's a great idea.

Good to know. I'd really appreciate an update if you do run into any issues.

Will do Mark

I didn't get time to try this today, guys. I was out looking at apartments all day and didn't get home til gone 6. Then I had to come to my mother's as I am still doing crap here.

It'll be next week now apparently, but if it turns cold I will have to stay put. I went into my flat today and I left the heating on 14 to make sure nothing freezes. When I turned on my PC the coolant temp was 7c. It was absolutely freezing in there and it's much milder today. I just can't be there in this weather
