NVIDIA adapts to the market and frees their displays

G-SYNC is showing some signs of defeat as today NVIDIA announced that several Adaptive Sync monitors have been tested and rated as G-SYNC compatible.  Adaptive Sync is the official VESA technology which is present in AMD's FreeSync monitors and it offers a definitive financial advantage over NVIDIA's G-SYNC as the module required for G-SYNC can add hundreds of dollars to the price.

So far only a dozen monitors out of around 400 tests have been rated as G-SYNC compatible, so don't expect to be mixing your monitors quite yet but it does imply in some cases the extra controller is not required for variable refresh rates with either NVIDIA's or AMD's GPUs.   The results of this test give AMD bragging rights for implementing adaptive sync in the most attractive way but this change could hurt GPU sales as users can now opt for an GeForce card paired with a FreeSync display.

Even if your display is not listed in those models, you can try enabling adaptive sync over DisplayPort and see if it works, though your results may vary. Ars Technica lists the models here.

"Besides being unexpected good news for gamers who already own one of these FreeSync monitors, this is also great news for gamers that want to add VRR to their Nvidia graphics card setup without breaking the bank."

Jeremy, you probably should have included this in your blurb above:

"... Starting with an Nvidia driver update on January 15, these G-Sync Compatible monitors will automatically be able to take advantage of G-Sync's basic variable VRR features when used with Nvidia 20-series and 10-series graphics cards. Owners of other Adaptive-Sync monitors will be able to manually enable VRR on Nvidia graphics cards as well, but Nvidia won't certify how well that support will work. ..."

So this means, all adaptive sync monitors "SHOULD" work, but only those select few are officially supported as gsycn compatible.

I actually have the Acer XG270HU. Looking forward to the Jan 15 driver update now

I see this as bigger news than the RTX 2060. Nvidia is finally coming to their senses. They probably don't see it that way though.

Except that Nvidia and Intel will be adopting the VESA DisplayPort Adaptive Sync(TM) branding from VESA and not AMD's FreeSync(TM) Branding.

Intel, AMD, and Nvidia/Many-Others are all menbers of VESA and make up it's committees, working groups, and executive board membership. Ditto For all those other Standards bodies like JEDEC, PCI-SIG, USB-IF/others.

Most of the GPU market besides Nvidia will be only making use of VESA's DP AdaptiveSync Standard and Intel's Discrete GPUs are going to be arriving sometime in the 2020 time frame. So between AMD and Intel that's probably why Nvidia decided to hedge its bets and also support the VESA DP AdaptiveSync standard.

Nvidia's RTX GPU IP is going to take a good while before most of the Open Source Graphics software begins to target any Nvidia custom CUDA 10, or even Nvidia's own OpenCL Implementation that needs some Nvidia/OpenCL extention work to support RTX/Turing's full feature set, ditto for OpenGL extentions. DX12 and Vulkan will definitely get Nvidia's graphics/gaming extentions that target RTX/Turing's new feature sets as both DX12 and Vukan are likewise extensable Graphics APIs with method calls already in place for CPU/GPU makers to add custom Graphics API extentions that are regisdered with DX12's and Vulkan's graphics APIs.

Nvidia is still free to continue its G-Sync IP and add things to G-Sync that VESA Display Port AdaptiveSync does not offer. Monitor Makers can vote with their Adoption Rates once Nvidia's GPUs work with the VESA DP AdaptiveSync standard. So time will tell for G-Sync usage and its continued existance.

Judging from the responses all around following this move, I like how nvidia is seen as a saviour by its users, liberate them from proprietary g-sync walled garden by piggybacking on a competitor's technology.

Question,

Since Gsync Altera chip is responsible for the frame doubling/tripling/quadrapling when game fps is under monitor VRR range.........what will happen?

In AMD part, AMD GPU is used to do the frame doubling/etc (low framerate compensation).
Does Nvidia have similar gpu based frame doubling?

from what I understand, gsync laptops can already do the frame doubling and those laptops have NO gsync module in them.
