[Vrzone] GTX 680 SLI Preview - Page 21

post #201 of 290

"For some reason, the third GPU almost always eliminates micro stuttering and has a less-pronounced effect on performance."

Now that is interesting.... That's the first time i've heard about 3-way setups having less microstuttering.

In a nutshell all it is really is the cards not syncing right when spitting out frames. SLI/CF use Alternate Frame Rendering and like all things aren't always exact on when they put each frame out. It affects *every* setup *ever* made. This is a fact.

My experience I've had briefly. I've owned a dual 6870 GPU set up for 30 days little over a year ago before switching to Nvidia for 3D Vision. I was experiencing blue-screens, micro-stutter and game lock ups. I'm sure I just didn't know what I was doing and didn't take the time to figure it out. The 10.2 drivers were really horrible at that time even for single GPU when those 6870's came out.

I've found one high end GPU has done the job and I've had no headaches that one hears about with drivers, games etc. Yet it doesn't scare me to try again soon. I'm looking forward to it with my 3D Vision to obtain higher than 60 FPS during 3D Vision gaming.

In deed there was an article on Tom's Hardware that explained what you said jtom320. What I've learned from that article explained a lot.

Please don't shoot me for my next paragraph it's coming straight from the article.

Nvidia users will have less micro stutter than AMD users. Reason being is Nvidia takes a more pro-active stance on addressing the issue of micro-stutter than AMD does. Hence Nvidia GPU's have less FPS in SLI and the very reason AMD has higher FPS scaling ability. Nvidia will have higher qaulity gaming with less micro-stutter on average because of this.

Micro-Stuttering And GPU Scaling In CrossFire And SLI
Quote:
We wish that AMD put more emphasis on balancing its dual-GPU setups. Despite a potential impact on average frame rates, some improvement to playability should be achievable while still demonstrating overall faster performance.
Quote:
Nvidia's approach is much more consistent, though its own SLI technology doesn't side-step micro-stuttering entirely.

Ok just let me know if I should wear a flame suit. Please keep it civil and refrain from name calling per OCN rules.

Edited to add: I was ninja'd by Mesmro on the link. ninja.gif

From what i've "heard & seen" Nvidia does a better job of tackling micro-stuttering than AMD does.

but you have 2 HD 7970s, why in Lord's name would you sell them and go to 680 when the difference is not soo huge and considering 89XX will be out later this year

If anything microstutter has been getting worse it seems (or maybe it's just because more people are aware of it). I didn't notice it on my 2x 8800GTX until someone pointed it out.. ever since it's all I see on multi-gpu setups.
Every multi GPU setup on the market has microstutter, this is fact. Depending on drivers, the game, and what FPS you are running affects how noticeable it is but it will always be there. Some people will never notice it (because it can be very minor in certain situations), other's will always notice it. It has nothing to do with the GPU and everything to do with the delay between the cards communicating - this delay will likely always exist because it's nearly impossible to get this to .000ms. There is no need to test every single card in SLI/CF to prove microstuttering exists on all of them. NVIDIA and AMD don't even deny this, it's how the technology works. Go read about how this technology works and what causes microstuttering, by arguing this you are just proving you don't understand how the technology works (no offense).
(I know someone is going to quote me and say that their setup does not have microstuttering, and all I can do is highlight what I said above " Some people will never notice it ".)

You would be a perfect subject for my "Is it SLI?" challenge. I bet you would fail....

You do realize that AMD and NVIDIA both admit microstuttering exists due to the way CF/SLI works? That means it exists on every setup that uses it, end of story. I feel you are just trolling at this point. Read the article and stop making yourself look like a fool, no offense. NVIDIA has even taken steps to reduce this, and so has AMD (but on a lesser note). It still exists, and it's still terrible under the right conditions, but barely noticeable under other conditions.

Some people around here care more about testing/messing around with different hardware than if it's a side-upgrade or not. thumb.gif

That kind of explains why i dont see it on my SLI 580's but i see it on my buddies 6950's. I have never " noticed " micro-stuttering on my system and as long as i dont notice it and it isnt doing any harm, i dont really care thumb.gif
