Workaround: FreeSync on nVidia GPUs

PCM2 said:
That's incorrect. (Had to make this larger so people actually see it as it seems to have flown under the radar, but is important).

Both TFT Central and I (PC Monitors main guy) have reviewed the Philips 436M6VBPAB and checked HDR functionality using a modern Nvidia GPU. It worked without issue with HDR over DP. HDMI is another story. I've tested numerous 'FreeSync' or 'FreeSync 2' displays with HDR using an Nvidia GPU and it works just fine via DP, as it does with HDR capable AMD GPUs and systems.

Also the AOC AG322CQ4 is a DisplayHDR 400 display, not DisplayHDR 1000. The HDR implementation also works correctly on Nvidia GPUs, although it is by very nature rubbish (like all DisplayHDR 400 'fake HDR' implementations).

Good info thanks PCM2. Maybe you can answer the question is VRR mandatory on HDMI 2.1?
 
I'm afraid I don't have the answer to that. I would expect it to be an optional extension rather than a mandatory requirement and it's possible a product could support some but not all HDMI 2.1 capabilities.
 
Nvidia is keeping Gsync alive by making sure adaptive-sync doesn't work on their cards. It's obsolete tech which they keep peddling for extra $$$. So yes they will probably close the hack, like they did with the hardware physx on AMD cards one.

How long they can keep it up for, who knows.

sorry missed this post. I guess that's the way it will be at least in the beginning.

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

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

Yep VESA had announced adaptive sync before gsync came out, tho gsync had been announced slightly earlier. Also first actual gsync monitors were not that far ahead of adaptive sync as it was all just installable module stuff rushed out to be ''first to market"

People have short memories - VESA, AMD, etc. no one had any interest in bringing variable refresh rate technologies to the desktop until nVidia started demoing G-Sync in action. AMD certainly weren't on the road to VRR it was a reactive development to G-Sync being shown off. The first G-Sync monitors were almost a year ahead of the first FreeSync screens and FS was obviously far behind G-Sync in terms of maturity on release with things like better refresh ranges, low framerate management and support for windowed modes being added in in some cases almost 3 years after nVidia supported them.

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.

IIRC the reason Nvidia decided to push for adaptive sync on desktops and eventually build G-Sync is because they added adaptive sync to some laptops or laptop prototypes and the test feedback they received was pretty much "this is amazing, we want it on desktops).
 
Only just read up about this, this seems like a really good idea. Been trying to find a new monitor but G-Sync is just too expensive. My brother's freesync monitor which was around £200 looks incredibly smooth.

Didn't even realise Windows 10 has the option to pick what GPU for each app. Checked on my work PC and it sees the Intel as power saving and the AMD as high performance.

Does that mean in theory, I could swap my 1600X for an APU, and I could get Freesync out of that instead of buying a dedicated GPU?

Potentially but the original reporter of this said that Windows 10 decided his AMD GPU was the best option for both power saving and high performance, which meant he couldn't pick the nVidia as the rendering device at an OS level. So it's a bit of a gamble until/unless Windows 10 is updated to explicitly let you customise that option. It would always work in games that let you choose a rendering device though.

Yup, which is probably the main issue at the moment since not many games will support that. Hopefully an APU will work and Windows will always treat the IGP as the power saving one. Having 2 discrete GPUs could be one reason why Windows is getting confused.

I probably won't replace my CPU with an APU anyway unless AMD has an 8 core APU coming up :p.

Not going to argue with you. But, you are wrong. AMD were on the road to VRR before Gsync was launched. Were Nvidia first out the door, yes, because they had the resources to bypass the all red tape with the VESA certification process.
