[PCPer] Frame Rating Comparison - HD 7950 CrossFire vs GTX 660 Ti SLI (full review) - Page 7  

post #61 of 542
I have a 660 Ti and coming from a 7970 I can tell you that both tear quite a lot (with just a single GPU). Even with vsync on I am getting tearing with this 660 Ti in WoW. mad.gif

i'll venture to this and excuse my psych 101 esp since its been since '94 for me; human sight is the most subjective perception we have. we see (or not see) what we "think" we see and that makes it difficult to show a person what they do not want to see. so i would suppose the video was slowed down to exaggerate the defects to show that they do exist. still even though the evidence in front of them, many folks for various reasons will still deny it.

Now first let me say I understand the Youtube reasoning but I think this is also the reasoning. Now hear is my question for you, if you cannot detect a stutter does it matter?

Now consider my question for a moment without fanboy glasses or anal retentive thoughts when it comes to performance data. I mean if you are playing a game and you do not see a stutter but the data shows there is a stutter does the stutter really matter?

Now does this mean the stutter should be ignored, of course not but I think a lot more is being made of it than needs to be. For example I have spoke to many people that are not buying dual card setups but this data to them seems to be relevant, despite the fact that the data shows in single cards the issue is not there.

I think we are taking a small pot hole and trying to turn it into a giant sinkhole.

are you using Adaptive v-sync. If you are, it shouldn't tear unless you're under 60hz

Any GPU will have screen tearing if the outputed frames are not synchronized with the refresh rate, plain and simple.

FC3 - terrible for AMD
SD - worse stuttering for AMD
BF3 - noticeably worse stutter on the nvidia setup

can't wait for the article and more tests.

AMD looks worse but they already said they have improved CFX drivers planned for june/july.

there are two "sides" to look at this.

objectively: the problem exists and ought to be addressed and fixed so to provide better quality of support for the product now and in the future.

subjectively: the problem exists but since it is not an issue with me at this time there is no reason to fix it.

so what are the consequences of either point of view?

when it comes to problem solving, it is always better to be proactive, solving an issue before it becomes a problem, than tertiary, waiting until it is an issue. its far from just being a PR move because it takes much less resources and time to fix it before it gets out of hand than to wait until later. as much as it isn't productive to make a mountain out of a molehill it is also undesirable to bury your head in the sand.

the answer is right in front of us; take a look at nvidia whom was aware of the problem and took steps to fix it. now look at AMD who wasn't aware so they didn't address any issue. prior to the new metric of "frame time" measurement was introduced most users were aware that a SLI setup produced less stuttering than a Xfire setup. now that there has been empirical evidence showing such, it is forcing users into an undesirable dilemma:

do i buy an AMD card which is better in single card usage but has problems if i want to upgrade to a Xfire setup? or do i buy nvidia which lacks in single card usage but has better SLI performance?

AMD addressing and fixing the problem, whether it is an issue for all users or not, will solve that dilemma.

Yeah, it is stuttering pretty damn bad in FC3. But my single card solutions also stutter a lot on it, so I think it's an AMD wide issue, not crossfire alone.

On the other two games, there's a bit of stuttering, but the biggest problem for me is screen tearing.

what if AMD let the problem (partially) away so they could announce a (free) solution later as a PR move?
