Should I wait for GSync?

[dragosudeki]

They are not the same technologies and they don't work the same way. Gsync and Freesync are not compatible, they share one part of their approach (vblank signal of varying length) but there is a lot more going on. AMD is not interested in making gsync compatible cards at all, their intent is to develop their own with Freesync and rely on the monitor manufacturers to implement it.

 

they're completley different technologies. What G-Sync is doing is making the monitor's refresh rate align with how much FPS the GPU is producing, so the timing between the frames drawn and frames displayed is perfect, creating a perfectly smooth image. What freesync does is different, and is going to be hard to implement on desktop monitors because of the display interfaces. Hardware always beats software solutions.

First of all how is GSync a software solution when it requires hardware as well? Does anyone know they are both different technologies? They both require the same input (DisplayPort). GSync describes itself as something that synchronises the monitor refresh rate to that of the GPU's frame rate. FreeSync is more detailed as it is described as using VBlank timing supported by the monitor to enable the variable refresh rate of the monitor. And AMD already supports this standard as I quote from AnandTech's  site.

 

AMD simply needed driver support for controlling VBLANK timing, which is present in the latest Catalyst drivers. AMD hasn’t yet exposed any of the controls to end users, but all of the pieces in this demo are ready and already available.

How do you know that GSync's module isn't just a interface that just supports that standard that AMD is talking about? I'm not saying that I am correct in which the GSync module will also work for AMD cards. I'm just speculating. I would also like to note that in Nvidia's response, they have said

 

DisplayPort already supports "everything required" for dynamic refresh rates via the extension of the vblank interval.

 

I don't think that AMD and Nvidia cards output different informations through Display Port, though I could be wrong. If the information is the same why would it not work? If you plugged and AMD card would the monitor not show any picture? Or would it? That is the question I want to know.

I never said g-sync was a software solution....

Oh, well then FreeSync is a hardware solution as well >.> Unless you made some random irrelevant point about how hardware solutions are better than software solutions?

True.

I think it comes down to the whole "can your eyes see more than 60fps" all over again.

Personally I think you will notice a difference.

 

I don't think it is in question whether you can see more anymore. Even IPS enthusiasts agree 120 is smoother. Eyes don't see in "FPS". 

 

*facepalm* Yes, I know. I was pointing out that on average, 90 fps is where people seem to no longer be able to tell the difference between it and 120 fps.

 

 

Not everyone is the same. Some people can notice it a lot more than others. I am also convinced that as long as I can see individual frames we have not hit the fps ceiling yet. However I can hardly push 144 so I am not eager for 180-240hz to come anytime soon.

 

IPS 4k gsync please!

 

IPS, 4K, Real 240hz, Oscillating backlight, G-Sync please.

Yes, it's about whether your brain can interpret / recognize the difference.

Linus put up a video of him vs a newbie to see who could recognize the difference between 60hz and 120hz

Linus (who has experienced it before) could easily tell the difference "like night and day"

But the newbie (who hadn't) had some trouble distinguishing the 2.

 

So it's kind of like training your brain.

Another example is how driving at 35mph feels a lot slower than normal after driving at 70mph.

Your brain is used to things wizzing past at a reasonably fast pace, but when you slow down things seem to go in slow motion a bit.

I actually had never thought of it from a mental standpoint but it makes a lot of sense. In Linus's other video on refresh rates he used a test subject who regularly gamed on 60hz and he could not tell the difference. While CS pros can tell when the framerate drops by ten.

I saw another study with 6 people and the same test with BF4 and all but 1 of them could tell the difference between 120/60 reliably. Personally I can tell you its night and day difference. I run one 60hz and one 120/144hz monitor and when I move the mouse pointer from one to the other its really obvious in the mouse pointers movement which is which. I am very certain I can pass a blind test 100% accurate between 60 and 120hz just within Windows in about 3 seconds flat. In games equally its so obvious, I look at my FPS sometimes in BF4 as its got choppy and its reading 65 hz or something. Having a high frequency screen just ruins you for the low frequency ones forever more.
