Workaround: FreeSync on nVidia GPUs

[DragonQ]

https://www.reddit.com/r/hardware/comments/998zkw/freesync_on_an_nvidia_gpu_through_an_amd_gpu/

tl;dr:

• Add AMD GPU to system and plug monitor into it;
  
• Find a game that allows you choose a rendering device;
• Choose nVidia card as rendering device;
• FreeSync works as expected via AMD GPU.

And yes, there are several caveats here including the fact that most games won't let you pick a rendering device and an artificial frame rate cap is introduced due to the added latency of copying frame buffers from one card to another.

Who wants to bet how long it'll be until nVidia either (a) find a way to disable this workaround, or (b) announce Adaptive Sync support by complete coincidence?

And the icing on the cake would be to run this setup with a 8700K...on a Z170 motherboard Hell, go full-on and make the AMD card a Vega 56 flashed with a 64 BIOS.

Take that, vendor exclusivity and your money-making shenanigans!

Yeah. Nvidia even goes down the route of making their own TVs instead of supporting HDMI 2.1 because VRR is mandatory, and it will kill Gsync.

People should boycott NVidia until they stop those practises.

The easy to say

But when there nothing else available to buy with the speed of a NVidia GPU it not possible..

When AMD get around to pulling there finger out there ass and make some fast GPU's then maybe boycotting NVidia will be an option..

Hold on mate. You blame AMD yet Nvidia is the one cutting corners and putting everyone in a closed ecosystem.
Get your facts together.

That you cannot run Vesa HDR1000 on a Nvidia card is not AMD's fault.
Nor that Nvidia isn't going to support HDMI2.1 because VRR is mandatory is AMD's fault.

These are Nvidia actions.

But you got remember NVidia bought out G-sync even before AMD had variable refresh rate and about 2 years before it was available on this new HDMI 2.1 version

Can you really blame nvidia for something they already bought out 2 years before it was even available on HDMI 2.1


Maybe am wrong on thinking nvidia was the first to bring out variable refresh rate (Please correct me if am wrong)

LOL.
Adaptive Sync is part of the Vesa eDP (embedded DP) since 2009!!!!!!

https://vesa.org/featured-articles/vesa-adds-adaptive-sync-to-popular-displayport-video-standard/

The moment Vesa announced in 2014 that Adaptive Sync will be added in the DP 1.2a AMD straight away supported it.
How you expect from AMD to support something that didn't existed on normal graphic cards until that point?

Same applied when came out with the HDMI 2.0 Adaptive Sync specification. Same when HDMI 2.1 was announced with VRR
All these technologies are exactly the same technically back to 2009 eDP

Nvidia released gsync in 2013 which is exactly the same tech, but is using their own hardware not the standard hardware coming with the port.
Yet on Gsync laptops, Nvidia is using Vesa Adaptive Sync through eDP not the own Gsync module.

And all these are similar to hardware ray tracing AMD announced back in 2013!!! Yet last few weeks everyone believes that Nvidia is the first company doing so!!!!!!!

Hell AMD supports Audio Tracing since 2013, yet Nvidia now started looking at it as a Gameworks module.

NVidia was out a good year with G-Sync before AMD came out with Freesync.

That "VESA ‘Adaptive-Sync’" link you posted is dated may 2014 were even yourself says Gsync was released in 2013...

Seems you blind? Did you read the announcement?

Adaptive-Sync is a proven and widely adopted technology. The technology has been a standard component of VESA’s embedded DisplayPort (eDP™) specification since its initial rollout in 2009. As a result, Adaptive-Sync technology is already incorporated into many of the building block components for displays that rely on eDP for internal video signaling. Newly introduced to the DisplayPort 1.2a specification for external displays, this technology is now formally known as DisplayPort Adaptive-Sync.

I would like to know if this actually works or not. Remember something like this came out before. They showed it working and everything, but, it didn't really work at all when other people tried it.

Ah, I get it now, slightly different than the previous attempts. Surely this would be as slow as Christmas with latency? Any benefit of using Freesync would be lost in copying from one card to the other. And surely there is a ton of input lag??

Though the information is lost in time these days, it was reported at the time, nVidia proposed bringing adaptive sync to the desktop way back to no interest from other parties and some resistance from certain parts of the industry who used it (usually eDP) professionally (just as an example air traffic displays) who saw it as possibly impacting on their income. So nVidia went away and made their own version, suddenly everyone else wants to get behind adaptive sync. AMD certainly weren't in a rush to support VRR until nVidia went down that road.

VRR is not mandatory in 2.1 (the only thing that is mandatory is that you can't slap HDMI 2.1 branding on the box if you don't support the full feature set - you have to use the HDMI 2.1 branding followed by explicitly listing which of the features and modes you do support).

Q: Can products have a combination of these features?
A: Yes, but it depends on each manufacturer’s implementation, so it is necessary to carefully check their specifications and marketing materials.

It is getting ridiculous how many falsehoods you are perpetuating to try and smear nVidia and detracting from the actual useful information you post on the AMD side.

Nobody argues, but believing adaptive sync it was "cutting edge" is a lie because it existed since 2009!

Can I have a link for that please, where Nvidia proposed that?

AMD were certainly on the road to VRR before Nvidia released Gsync.

AMD missed the boat on that one. VRR is a game changer for me.

I've tried to find the information online a couple of times when it came up recently but it seems to have dropped off the map. It definitely happened I saw it myself at the time.

I do agree, though it is kind of moot, that it isn't cutting edge - VRR has been used in professional displays and signage going back possibly to the 70s.

Yet here we are HDMI 2.1 will be coming shortly on all displays (including TVs), and Nvidia because it doesn't want to support it is even making own TVs!!!!!

And HDMI 2.1 with VRR (is compulsory) costs to manufacturers $0.05 and HDR Gsync module how much?

Why do you think they should support it when there most likely making a huge packet out of there G-sync

True. But that's exactly where we started and you came with the history of gsync.
You blame AMD for not competing, yet you praise Nvidia for their closed technologies milking their customers.
And this is AMD's fault.

No is your fault for support Nvidia's practices.

Maybe it true I praise Nvidia for giving us G-sync as am happy with my G-sync monitor and my G-Sync gpu..

As I don't really see a problem
If you own a Nvidia GPU then buy a G-Sync monitor
If you Own an AMD GPU or going play an xbox on it then buy a Free-sync monitor
