NVIDIA Has No Plans for Adaptive Sync Support on Maxwell, Prior GPUs

In case anyone's been living under a rock (and in these times, if you can do that, I probably envy you), NVIDIA at CES 2019 announced it was opening up G-Sync support to non-G-Sync totting monitors. Via adoption of VESA's open VRR standard (Adaptive Sync, on which FreeSync is based), the company will now add support for monitors that usually only support FreeSync. The company also vowed to test all configurations and monitors, with a whitelist of automatically-enabled panels and manual override for those that don't pass the certification process or still haven't been subjected to it.

Now, via a post on NVIDIA's GeForce forums, ManuelGuzmanNV, with a Customer Care badge, has said, in answer to a users' question on Variable Refresh-Rate support for NVIDIA's 9000 series, that "Sorry but we do not have plans to add support for Maxwell and below". So this means that only NVIDIA's 1000 and 2000-series of GPUs will be getting said support, thus reducing the number of users for which VRR support on NVIDIA graphics cards is relevant. At the same time, this might serve as a reason for those customers to finally make the jump to one of NVIDIA's more recent graphics card generations, in case they don't already own a VRR-capable monitor and want to have some of that smoothness.

Not surprised, because Maxwell and below don't have DP1.2a or HDMI 2.1 which are minimum hardware requirements for adaptive-sync. Maxwell has HDMI 2.0, not 2.1 (which adds VRR).

Good point. There's so much dis-information on this whole thing... like reading they were "enabling" G-Sync on non G-Sync monitors. Yea, right.

"NVIDIA's 9000 series" should be 900, iirc.

They can easily do it but they are trying to get rid of their surplus of GTX1000 series GPU's.

Yeah, I'm not sure why people were expecting something to work that isn't physically possible on the cards. Adaptive sync is not just some kind of software switch that can be turned on and off, there has to be hardware there to support it.

No, they can't. The cards don't have the hardware necessary to use adaptive sync.

We all knew they nerfed DP and HDMI for that reason. Nvidia has been a running joke about not being up to snuff on those.

No different than AMD not adding instructions to phenom ii based cpus that were already two generations old on Intel products.

Companies cut corners. I doubt this was meant to prevent users from using a technology that wasn't even out yet. Probably a design situation in which it wasn't out when the card was designed and offered no real improvement or reason to add it before release.

Yes, I'm sure that 4 years ago when they were designing the cards they said to themselves "You know, in 4 years, we're going to enable adaptive sync on our video cards, so we better use DP1.2 on these cards now, so they won't support it when we enable it 4 years from now."

Not to mention they were pushing their own standard. Is like mocking Microsoft because they didn't put bd on the x360 and had to do in the xone.

And then complaining that the Xbox360 doesn't play blu-rays when they enabled the XboxOne to play them...

How does nobody in this thread know that the 900 series has display port 1.2, especially an "Editor & Senior Moderator"...

DisplayPort 1.2 is not the same thing as DisplayPort 1.2a, is it?

Maxwell lacks DisplayPort 1.2a, which AMD has had since R9 290-series (circa 2013).

Next time don't be a dumbass and do your homework before calling out someone who wields a banstick.

Could've informed me of that without the flex, but thank you for correcting me.

Its like nVidia hate train.

Im personally quite happy they add it to what they add it. Especially since I kinda do want Adaptive Sync monitor. And nVidia GPU.

This should read "NVIDIA's 900 series".

Regardless, VRR isn't that useful unless the framerates can't match or exceed the display's refresh-rate. Most GPU's since the GTX660 and above can be configured to run well with standard vsync enabled.

R&D time for a long retired product line. Pascal, yes.

GCN may produce the HDMI signal in the GPU itself (where driver can add features) where Maxwell may use an ASIC that's fixed function. The only thing GCN hasn't been able to accommodate with driver updates is increasing bandwidth.
