From what I've seen it's a Far Cry 3 problem more than an AMD/Nvdia problem as its terrible on both.

What if AMD purposely released Bulldozer with its known flaws, slowly fixed them with Piledriver, only to return to giving each core its own decoder in SR, and fixing the rest of the issues from the Bulldozer design, they did all this in order to have positive PR for Steamroller!

The answer to your question is NO.

If AMD could've delivered a smooth gaming experience for CFX from the get go, they would have.

just throwing the idea out, i know it has no sense but worth mentioning even if it is just comedic value.


but it could be partially true. what if the early release of the 7970 caused them either not spotting the ,ain reason for the lack of smoothness (i.e. the proper solution) or couldn't fix it in time and seeing that for the most of the 7000 series span they ran away with it until recently so working on it then might be in favor for their PR.

i suggest reading AMD Comments on GPU Stuttering, Offers Driver Roadmap & Perspective on Benchmarking if you haven't. in it states that AMD believes that the issue(s) has also hampered overall performance. so to take a risky strategy such as that ought to have everyone question the sanity of the people involved in the decision making process.

and i'll refer to that article again on a side note. my god look at what tool they are using; GPUview. they are stumbling around in the dark, throwing rocks at every noise they hear . . .

To be honest I'd like to see some blind benchmarks, someone does the setup and benches and another person interpret them without knowing the video cards until after they analyze it. Just name it source 1 and 2 and let people rage on the comments before revealing who's who.

yeah i agree, just wanted to throw the idea even if it's for comedic relief. (but then again you don't have to be sane to be successful rolleyes.gif )

The only real issue I'm seeing in these videos is that the results aren't in sync. I would chalk that up to the fact that it's hard to match step to step on both setups. The 2nd issue I'm seeing is the horrendous tearing between both sets of cards. Yet some only want to label CF as having runt issues, lol. The 3rd thing I'm seeing is that CF does seems to have delay in panning. Which doesn't look at responsive or as smooth as it should be. Which looks to me that CF is actually providing lower frame rates. It would have been nice to see a frame rate counter when those videos where provided. That would tell the whole story as to what I'm seeing.

But as I'm reading the replies on those videos is does make sense, to me, why vsync is being questioned.

Its okay if they denying it based on their own experience with xfire but the videos (which is 50% slower) clearly show the truth. The thing is, we don't need a superhuman vision to notice the stuttering in the videos.

Definitely, but you've got some people here (Who coincidentally own GeForces) who act as though it's a night and day difference in the real world.
I don't think many people are actually saying it's not real, they're saying that 1) a short term solution is to frame limit/vsync (Different things but both fix it for now) and 2) it's not that noticeable for a lot of people.

If you're going to get 60 minimum, you can use vsync to eliminate it...Or you can frame limit and hope for the best otherwise.

I agree. I want to see this because TRs report seemed to show the GTX 570 being close to a HD6950 in latency.

No-one but the deluded are saying "Don't bother fixing it, AMD!" at all, as some people can/B] notice it, most of us who are saying that it's not an issue with us are just saying "This doesn't mean you shouldn't go for AMD over nVidia if you originally were, you may not be affected and there's a short term solution as well."

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

Majin SSJ Eric was having problems with that, too.

Didn't AMD have a never settle bundle that included sleeping dogs and far cry 3?
