The G-Sync on FreeSync Thread

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

https://www.overclock3d.net/news/gpu...ync_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

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.

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?

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.
