Have software that recognises the consoles and allows it to use the G-sync module?

It be great if they made a TV that supported G-Sync over the display port input and supported Free-sync on the HDMI inputs
But I can't see Nvidia doing that...

The same way as there no way AMD would build in G-Sync support if they made a TV

I am sure it would be possible, but, would Nvidia allow that? IT would be eating into their own business and imagine the how on the talk on websites and forums would go? If you can use Freesync and Gysnc on a TV why can't do the same on my monitor? etc. etc.

It's not the same thing though. VRR on HDMI 2.1 can be used by anybody. Whereas Gsync is a Nvidia only thing, so AMD would have to buy the module from Nvidia to install it in a TV.

I bet they'd come up with a lot more reasons for why they shouldn't do it than why they should.

Good point, I never thought about that. While as said it's unlikely AMD would do it maybe that Nvidia could come to see it as a strong selling point for their G-sync TV's &/or Monitors.

The XB271HU is still going for £600 yet I bagged one for £390.

I thought I did alright last year getting it for £550! Monitor prices have gone mad.

Intel reconfirms adaptive sync is "coming in the future": https://www.reddit.com/r/intel/comments/9bmu1m/intel_reconfirms_adaptive_sync_future_coming_in/

In theory, shouldn't KBL-G support freesync? Just Intel blocking it via driver at the moment...

It was a b-grade from OCUK but luckily has minimal IPS glow/no backlight bleed. I think it was returned due to a minor firmware fault where a vertical strip of pixels from the center of the screen relocate to the left or right edge of the display (solved by an alt-tab out of a game or power cycle) but even that seems to have stopped or become extremely rare. I was very lucky!

Rather late to the party, but Linus has posted a video testing this out with an APU. With his viewership this should raise awareness and perhaps shame Nvidia into action. Once Intel iGPUs have adaptive sync they really won't have a choice.

Intel supporting Adaptive Sync is pretty pointless until they have a semi-useful GPU.

It would be very useful for Nvidia owners though.

This isn't good news for AMD.
If this work around works with absolutely minimal FPS loss with an Intel CPU doing the freesync and an Nvidia GPU doing the rendering, then AMD lose a unique selling point. I'd have bought a 1080 rather than a vega 64 for example etc.

That, or it will finally raise it's profile enough for Nvidia to slam the brakes on it like when people were using cheap Nvidia cards to add PhysX for AMD GPUs...

I think it would be quite hard as the frame cloning / GPU switching tech it is baked into DirectX and Windows 10. If it just relied on Nvidia's Optimus then they could put a stop to it more easily.

Freesync / Adaptive Sync was always an open standard, so the only thing giving AMD a unique selling point is Nvidia's instance on only supporting their proprietary tech.

haha APU shortage incoming

Ignoring semantics, if you can use an Nvidia GPU and an Intel IGP to utilise adaptive sync then you don't need to buy an AMD GPU to use your adaptive sync monitor to its potential. Which is something you have to do at the moment.

Well you could also just use the Intel IGP (or at some point even a discreet Intel GPU) and make use of an adaptive sync monitor. No need to buy AMD or Nvidia!

You could say the same for AMD’s Mantle which became Vulcan and is now being used by Nvidia for RTX. In both cases AMD chose to make the standards open to the benefit of all.

If you don't actually want to enjoy your games, then sure.

I don't think amd look at it like this. AMD focus is open source. They was the first to bring this open method to the world.

They have successfully done this, their job here is done.

While not the same thing has Adaptive-Sync TressFX has also done a similar thing. Shadow of the Tomb Raider an Nvidia sponsored game is using TressFX but because this is open source the devs have changed the name.

Amd focus is always to bring open source to the industry some successful others not quite.

I would be pretty peeved if I was running AMD. Like Martin said, it is a huge selling point and Freesync is far cheaper than G-Sync screens, so a main selling point is now gone.

I also feel AMD don't have the resources to push tech as much as NVidia and hence they put it open source.

we knew from the get go it could be used by others, the whole idea is to try and standardize something which they achieved getting it into the hdmi spec, so theres nothing to be peeved about. even when intel support it, your still using a hack to get it working on an nvidia card. the only people who will be annoyed by this are nvidia themselves for loosing out on those gsync profits... i/e why would anyone buy a gsync screen when the same screen costs less with freesync.
