Nvidia Explains Why Their G-Sync Display Tech Is Superior To AMD's FreeSync

If the a driver has to be tunes to each panel i can see this leading to issues are the number ramp up given how Crossfire support is handled. As for the ghosting thing we need to see far more examples.

Thats with both technology's with different screens with freesycn/gsycn on and off. Given than gsycn/freesycn both have more control over the panel there MIGHT be some merit to the current ghosting issues but we need far more data.
 
From this video, it is inherently clear that the BenQ and LG are suffering from Ghosting. Now it is down to the individual if they are happy with that or not and some will see it whilst others clearly won't. I am very susceptible to these things and personally would hate it but that's just me.

Isn't the point that VRR makes ghosting worse due to the way the panel is being driven at different refresh rates? how can that not be a Freesync problem if NVidia have a solution to reduce it with G-Sync?

All monitors are DP1.3a compliant so clearly they meet the specification that AMD wanted.

Exactly, VRR can make ghosting worse, Nvidia created a hardware solution to help deal with this, Freesync has no hardware so the solution would have to be added to AMD drivers.

Really, he way I see it Freesync is just a partial solution, better than nothing but quite obviously it can't do as well as gsync because it is missing hardware on both ends. Gsync it doing a heck of a lot more which has the positive effect of reducing ghosting, as well as eliminating tearing and stutter when crossing the minimum refresh rate of the panel.

Freesync seems to work well in the middle ranges but has issues when frame rates go to the extrmees, that is when Gsync hardware comes in to its own and improves the user experience in a way that Freesync likely can never match until they create a gsync like module.

But they making it out like it's freesync making that happen. When clearly that isn't true.

Pretty dramatic difference and it is clear why the SWIFT can command that kind of price, it is clearly in a league of its own.
 
Ok so im buying a new 27" 1440p 120/144hz Screen this year, more than likely to go with a 390X (depends on how the card is) if not a 390X then a 295x2, i hate the thought of lining Nvidias pockets with cash, so basically, is freesync worth the investment or is G-Sync and Nvidia the better option?

All i want is 1440p and 144hz as much as possible, i play MMOs FPS and D3 mainly :)

You have a strange way of phrasing things.

yes, the panel creates ghosting at high refresh rates, not freesync, but the issue is when you are dealing with variable rate refresh VRR you have to do something special to help eliminate ghosting. Nvidia does that special something inside the gsync module, in hardware that is tuned to the panel. Freesync is missing that hardware and so it is up to the driver to try to do something about the ghosting, and that has to be specific for each panel type. Currently AMD's freesync drivers don't do that, so ghosting is visible.


So does Freesync cause ghosting, no. VRR at high refresh rates causes ghosting and it is tricky to deal with. Freesync has no mechanism for dealing with it, gsync does.

This isn't something specific just to a couple of models of freesync monitor, it is an inherent technological problem that will affect all monitors doing VRR at high refresh rates.


It is clear AMD have traded a hardware solution for a software solution. This is often a good move (lower costs, easier to get widespread uptake, easier to maintain/upgrade). But it does require good software development, something AMD is lacking in wrt GPUs. Nvidia gets the monitor manufacturer to tune gsync for the specific panel, removing the need for Nvidia to maintain support for different panels.

Yer agreed and no buyers remorse for me and I was more than happy to pay that after I got it. Prior to purchasing, I felt it was OTT and too expensive but after getting it, my mind was changed and in terms of monitors, it blows everything away I have ever owned.

If anyone asked me what to get and they owned nVidia, I would have no problems advising the Swift.
 
I think most of us knew gsync was a superior technology. AMD tried to replicate and failed, but hats off to them for at least having some sort of a solution for their users to use :)

Si, it would be wiser to ask that in the monitors section, as I doubt you would get a reasoned response in the GPU section (might be wrong). :)

I would be interested in seeing the results again but after the BenQ has been calibrated.

Depends what you mean by calibrated.
Sure, you could put the brightness right doesn't and reduce the contrast and the ghosting will reduce but that is irrelevant, that is like saying if you switch the monitor off you don't see any ghosting.


Ghosting is always more apparent with a brighter screen and high contrast fats movements so it is obvious reducing both of those will reduce ghosting.

That isn't a solution just like if you think the colours are wrong on your monitor then switching to black and white is not solution.


There is nothign wrong with these panels, they display ghosting in the scenario when you expect it do occur, freesync just doesn't have a solution to this problem at this time, gsync does.

I'm not sure they tried to replicate gsync, if they did they would have created their own hardware module. Freesync can solve part of the problems in a very cheap and easy way but have issues in the high and low refresh zones.

The comment that the price of the SWIFT has barely dropped is a very valid point- the market has decided it is worth that price.

Good call, tbh as much as it really pains me, im tempted to hang out for the 980ti if it comes and just buy a damn G-Sync screen like the Swift, AMD are beginning to look amateur hour now :( lack of any kind of news coupled with having to spend money before the wife discovers it means i need to buy soon lol

I am massively biased as you well know and my 290X has been a great experience in truth (ignoring my 144Hz issues) but I just can't help feeling that nVidia go that bit further (and at a cost for sure). I can't comment on Freesync, as I don't use or have ever seen one in motion but the Swift has been a fantastic monitor. It isn't till you try it do you see what you didn't see.... I know that doesn't make sense but tearing and stutter are gone and you notice how bad it was before. Having no G-Sync for the past 2 weeks has just made me not want to play games in truth and that is how G-Sync has improved my gaming.

Not much else I can add really and only you know what your eyesight is like and what you accept in games.

Yer, if they weren't selling, they would have dropped big time.
