Mantle and Frame Latency



For NVIDIA, the experience is actually slightly more erratic at 4K than with Hawaii, indicated by the slightly more variable orange line in our Frame Times graph.



SLI and CrossFire really make this stutter effect worse, though the average frame time variance for the GTX 980s are worse than that of the R9 290Xs. That happens in both 2560x1440 and 3840x2160 resolution testing, giving AMD the performance and experience nod here, regardless of what the "average FPS" is telling us.

If you want smoother gaming, its got to be AMD :D

Oh...my...god...he has 2 at 20ms and not five as you previously alleged, you have 4 over 16.6 (the cut off for smoothness at 60hz) And another 2 at over 38ms which would be a full three frames skip

You have a total of 10 repeated frames vs 2

Objectively, the nvidia graph is 66% or 80% perceptually smoother

I said he has 5 over 15ms witch he does, could even be 7 but his placement of other windows wasn't the best.
 
Good find HumBug :D

Results dont Lie

AMD give the better frame latency, my results with no Sync are even better than the Gsync results shown here, less spiking, smoother render times... Ok I had one bad spike with crossfire enabled. But you can see my Single GPU results are even good.

Haaaa
 
Your still missing the point of what spikes are actually important for perceived smoothness and why, if a slightly flatter graph overall but with larger and more frequent spikes makes you happy then I will leave you in blissful ignorance

I think that is wise. :o

They used Nvidia's own Fcat, the same system that they used to prove they had the smoothness upper hand a couple of years ago, AMD admitted they had to work on it, and so they did, this is the result.

Will Nvidia now admit they need to work on their smoothness?

No chance, Nvidia are to good to admit anything.
 
I thought the gaming experience was about how it looked on a screen not what a graph looks like.

What I have found using cards is visually (not fps) most of the time 2 GPUs look better than 1, 3 look better than 2, 4 look better than 3 (you can get the odd failure with 4 due to stutter). The same goes for both AMD and NVidia.

Having said that if we were to look at graphs for some of these setups they would look awful, but we don't look at graphs when we are gaming, we look at the screen and that is all that counts.:)
 
The nvidia graph is zoomed right in, Yours are upto 60ms zoomed out, If you want a comparison on users rigs for this it will never be accurate.

If the smoothness is better on amd then at least we can agree that nvidia has faster cards playing on bf4.

Saying mantle is smoother than gsync because a graph shows it is laughable to be honest, if you knew anything about gsync you'd realise frame times mean practically nothing when using it.

That's the way I look at it but people will use whatever tools they can grasp at to make fallacious points in favour of their preferred GPU brand. Having tried both of them very recently there just wasn't any perceptible difference for me between the two brands Mantle included. Both DX through nVidia and Mantle through AMD worked well and felt smooth.

If we're at the point in the argument where you can only tell the difference by analysising graphs then I think everybody should be happy that performance is good and stop posting nonsense graphs and claiming victory.

Can on go by what I seeing in the Results.

Its this reason when I have said in the past Gsync or FreeSync wont give me any benefit in smoothness because I use NO sync.

The only gain I will see is Screen tear gone.

Vsync On = Stutter = Input Lag
Vsync Off = Screen Tear = Zero stutter or input lag

Gsync = Above Fixed
