It does add latency, in this case it helps smooth out another aspect of the SLI scaling. They took the minor latency hit from developing that tech, which in turn helps the SLI scaling and overall evens out the latency per frame. Meaning a small trade in latency for a more even performance. Might be why Nvidia's SLI doesn't scale or give as many FPS as you would think compared to what CF offers. Titan's poor scaling? The question behind that should be, do you as a consumer find it more acceptable to take that latency (resulting in lowerfps/performance hit) with a smoother frame output or take the other option. Without the added tech, you might get a higher FPS but then suffer the same issues CF is currently going through.

Sometimes adding latency for a better outcome isn't a bad thing, in the end most people (rumors, gathered reading, disprove if better informed) will say SLI is a bit better than CF in overall feel. So was it worth it for them to develop that tech and add another layer to the driver/software stack?

The only SLI setup I had was 2x460, I can say it was BUTTER smooth when things were set up right. I haven't played with CF, in which case I don't know how to compare it. Those that have should really be the only ones to justify that question, if they feel SLI is smoother and a majority take that stance I think the answer would be obvious (or if a majority feels it doesn't matter, you still get an obvious answer).

I think it just goes to show you that no solution is perfect, although in the case of AMD it's basically no solution lol. For me personally it's a non issue, I either use Vsync or a framerate cap so it's irrelevant to me.

I should note, my SLI 470's felt no smoother than my CF 7950's.

I'm in the same boat mainly, I can't stand tearing. and I mean, CANT STAND tearing. I'd ignore micro-stuttering before tearing, tearing just drives me up the wall.

And you are right, neither company has a good solution as of now. The only difference I see is one company has more experience than the other, which should be obvious. AMD does extremely well at pushing the innovation, just when it comes to refining and optimizing they aren't the best. They do seem to do better competing with Nvidia than they currently compete with Intel, as I believe they lost that IPC/Thread battle a while ago. I think they knew that too, hence the new uarch and BD was born. They are quick to get new ideas out and do relatively good with those new ideas, just currently they don't have the development backing as other companies. Which is what I think is the major downfall, hopefully some of their new ideas take off better than past ideas and that changes.

The point is, if AMD had some type of frame metering in the same way Nvidia has, you would minimize frame tearing anyway

I'm sorry, but that's complete crap...Tearing is just from having half-frames rendered, this can happen when your monitor that refreshes 60 times a second gets two frames halfway through drawing a frame and is irrelevant of card maker, whether you're running AMD, nVidia, 3DFX, Tseng Labs, S3, etc.
It's not non-nonsensical either...I don't usually notice input lag from vsync but I sure as hell notice the tearing. (And have on all of my nVidia cards at one point or another, ranging from my two nVidia TNT2s to my GTX 470)

Are you getting above your refresh rate? Because you might just not notice the tearing. I sure as hell do and don't notice the input lag generated by vsync, even if I had something insane like Titan quad SLI I'd still enable vsync as there's no point in rendering frames you can't see. (ie. 60+fps on a 60Hz screen)

Also, if it's fair enough to complain about the input lag generated by vsync it's sure as hell fair enough to talk about tearing and not like it, I know I can't stand it.

and thats wrong for a "moderator" plain and simple thumb.gif

He's not really biased that much, if at all...I can think of other mods that have it much worse.

This is something people seem to have forgotten...nVidia stepped it up with Kepler, before this their GPUs were pretty equal in terms of latency according to the TR review that started this entire thing.

Agreed. I've noticed the input lag generated by vsync in only a handful of games, but tearing I've noticed in every game I allow to run over 60fps..It's also a hell of a lot more annoying as it's not something you can just get used to as it always happens, tearing happens randomly and completely ruins immersion to me.

at least my crossfire does not suffer stuttering such as this in the video.

690 sli . . .

that hurt my eyes.

it's the game man, it's in BETA and read the comments, they all have the same issue, even the HD 7850..
