And unfortunately only 10 series and 20 series cards are supported. I was excited since I have a freesync panel and a 970 until I found that out. Feelsbad

you have link on this part?

I just watched a video, I think from ExtremeTech, where they showed off what using this on a non verified monitor looked like. The worst offender was the display blinking off kind of randomly for a split second. Something caught me by surprise, he said it would do it even if you used an AMD card, and that's where I started to doubt this whole thing, free-sync monitors should all just work fine with AMD cards. I think that nVidia is trying to force a certain window of compatible FPS that some free-sync monitors can't handle. If that's the case my monitor should work fine as it goes from 48-144hz. We'll see in a week I guess.

Flickering monitors happen on AMD hardware as well. I'm not 100% familiar with how it all works, but I've seen people say that its due to monitor manufacturers basically lying about their specs and forcing monitors to run in ways that the panels cannot handle. AMD does some work driver-side to try and force freesync monitors into compliance, but it doesn't always work. Even on some higher-end panels (like the LG ultrawide Nvidia is using as an example at CES) there are flickering issues. I believe some issues with these monitors are solved by changing some settings or doing various other tweaks as well, but it seems like Nvidia is just running them with out of the box settings and is not going to do monitor-by-monitor fixes in their drivers.

Hmm, I wasn't aware of that. My monitor always just worked out the box. It's an Acer XF270H, I've ran it with an R9 290x and an Rx 550 and both worked flawlessly. I just upgraded a couple of months ago to a 1070 and I'm really missing free-sync. I don't know if they've tested any older free-sync monitors, or just ones that are currently in production.

Yes it is and no it doesn't. Nvidia put Fermi GPUs into legacy status in April of last year and has only been releasing critical updates for it since then. That critical update support ends this month.

Its too bad Nvidia didn't release a list of which monitors they tested, how they were tested, and why they failed. While I imagine there might be good legal and/or business relations reasons not to do so it would be interesting to see the results so the end user has a better idea of what to expect when using a non-certified monitor.

From their keynote video, the implication I got was they're going to test all available monitors eventually. At that time, done 400 out of 600+. In same video, they showed examples of what was bad behaviour, blanking or strobing. On their website they mention a variable refresh operating region of at least 2.4x. Why that number, I don't know.

Oh, damn! What a great way to start 2019. I don't have a freesync panel either but, I'll be curious how the "Not worthy" monitors will play along with this.

I'll let you know when the driver update releases, my panel isn't on the "worthy" list.

I know they plan to do all of them, but it would be nice to have a list that mentions exactly why each failed and how they did their testing. 2.4x is the requirement for low framerate compensation (LFC). LFC is one of the requirements for Gsync.

So, I've been doing some digging and I may have found out a reason for Nvidia not enabling VRR on 900 and prior cards. The VESA VRR standard requires Displayport 1.2a. The 900 series only supports the base 1.2. This means that they cannot support VRR over Displayport. It seems like they, along with all current Nvidia cards, lack the ability to do VRR over HDMI as well, which would explain why this update only allows VRR over displayport.

There's nothing in hardware preventing them from upgrading the DP output to a new standard unless the hardware is literally running a ROM.

in pcworld article on gsync vs freesync i linked eariler

states nvidia has requirements besides lfc too

 

Nvidia hasn’t publicly detailed the requirements, but representatives tell me that the company works directly with panel makers like AU Optronics to optimize refresh rates, flicker properties, response times, and visual quality; then works with the display makers (like Asus and Acer) to fine-tune the on-screen display and more. Every monitor is calibrated to the sRGB color gamut.

and in the nvidia blog there was nothing on what series it supports just they are testing with 10 and 20 series

 

G-SYNC Compatible tests will identify monitors that deliver a baseline VRR experience on GeForce RTX 20-series and GeForce GTX 10-series graphics cards, and activate their VRR features automatically.

 

but you could be on the reason why too but then again theres this article too

https://www.guru3d.com/news-story/nvidia-releases-firmware-update-tool-to-support-displayport-1-3-and-1-4-displays.html

 

so it might be a ymmv type thing on older cards

News to me, shows how long it has been since I put my 580 in anything, last time it had updates. Still, they support just past that now and did support them until 6 months ago, point being they typically support them for many many years, basically as long as they are still used and still able to push some modern games alright, otherwise face pissing people off. Remember how long people were still using the 8800 and getting driver updates?

I think it may be possible to do a soft update for that, but it makes a lot more sense. They both have the same bandwidth, and I think it literally isa firmware thing, but I could be wrong. Still, an actual reason, and they may not be able to fix that. I was able to find some sources in 2014 finding it odd that the 9 series would not have 1.2a for this exact reason too. My main annoyance was that gsync was supported as far back as the 6 series, and it's definitely possible, but probably harder.

That's exactly what Black Friday/Cyber Monday is for. Consumers to buy last year's products "on the cheap" to make room in retailer inventories for new product launches the following year.

 

"On the cheap" is a stretch, since most retailers slowly bump up the prices over the preceding months, then reset them when Black Friday hits, giving the illusion of a great deal.

while Nvidia takes a $200-$500 cut for every Gsync monitor

NVIDIA isn't just taking money from people for nothing there is an additional cost due to having a G-Sync module integrated in the monitor.  That hardware and integration isn't going to be free.

You’re right, it isn’t, but it means to get Gsync, due to the added module price someone will have to step down from a 2080 to a 2070. Or, they could keep the faster card, get a FreeSync monitor, and have a higher FPS experience.

Snagged a Vega 56 with 3 games (XFX hooked me up. Newegg did not offer the gift) for 330 after 20.00 rebate. Not complaining :)

Lian Li O11 was in my top 3 new case choices at the 150 max budget but I went with the 570X... The Razer Edition O11 ships in Feb. I ordered the 570X weeks ago when I now know I should of waited. The Razer will sync up with all my other Razer rgb items where with the Corsair I was limited to their light strips, fans, exclusive hubs etc. 

Still getting the LL120s of course but only a 3 now instead of 6. So with the lighting that comes with the razer pre installed and less "diplay" fans needed Ill be saving 250-300 at least! and I can also add a figure inside because I like it (NO pop funco bobbles heads. Gross)

Higher FPS, but at the expense of the screen. If you want a FreeSync monitor that is comparable to a G-Sync monitor (which is to say, has good variable refresh rate range, adaptive overdrive, light boost and all the other stuff that's standard on G-Sync) then it will not be cheap. It might not even be cheaper than G-Sync. 

 

I don't think people realize how high quality and all the features that are included in G-Sync. There is way more to it than just resolution and refresh rate (which is what most people look at).

I've been looking at monitors, comparing prices on Newegg, and usually when looking at two monitors of similar quality, brand, and ratings, the Gsync was about $200 more. Soon, we'll have third parties comparing these panels on the same card, and we will see a real side-by-side comparison, instead of testing FreeSync+Vega vs Gsync+GTX!

Got any links to those monitors you compared, and did you make sure they had the same feature set, such as strobing backlight and adaptive overdrive?

No clue about extra features, but backlight strobing would cut brightness in half and significantly increase the chances of eye strain and headaches...
