Buggy card with non-functional boost? Or fluctuations from 850 to 925mhz? They won't mention or test with powertune +20% (eliminates poor cards from random jumps).

Heck just put in a 7970 Ghz and compare.

I thought of this as well, as I had a Sapphire 7950 with that problem. I wrote to Scott at TR and asked if he had thought of this. He wrote back that he thought that the card itself could be the issue, so he also tested another 7950 without boost. The results were the same.

I made the mistake of updating from 12.8 to 12.10. My system hasnt been much different when playing BF3, but black ops (first one) has been terrible. Seems odd, my system specs are more than enough for the game and it was butter since I built the system. The graphics are nice looking, crystal clear but I get sever stuttering at times. I think I need to take a look at power cycling.

TH has a FC3 article up. For the high detail settings, they bring up SLI is smoother than crossfire. From the min/max numbers it's not that obvious, but the plotted fps show some issues.

Far Cry 3 Performance, Benchmarked

And in Eyefinity, its smooths out again, the dotted green line is not better than the dotted orange line, in fact the dotted green line looks a little worse.

Averaged FPS graphs like that do not show MS at all. They're misleading. This is the whole point of what this thread is. Why people keep posting averaged FPS graphs, I don't know.

I know but still the Averaged were better.

Well, at least you're admitting that you're trying to be misleading I guess.

No as it was in reply to what he posted and linked, don't try to twist things as you have a habit of putting things into peoples mouth.

I just debunked his worthless post that's all, he showed bad average and my reply was better averages, Job done and move on.

Countering a post from the same source is not misleading whether that post was on topic or not.

My summation of this thread.

"Hey, the fluctuation in frame time on AMD cards is bad according to X"
"Here, look at these averages"
"That's not really relevant here"
"Look at some more averages or other data that doesn't address what this is about"
"Ok, that's not the point"
"LOOK AT MY 800 AVERAGE FRAME RATE GRAPHS OR MY OTHER GRAPHS THAT ARE SOMEWHAT RELATED BUT REALLY NOT THE SAME THING AND PAY NO ATTENTION TO ANYTHING ELSE"
"Are you people for real?"
"Hooray for our side!"
"Erm, k"

And your reply to Notty.


Well, microstutter will not appear on a plotted FPS graph that is averaged per second anyway (that's the whole point), but even like that, that looks pretty bad.

Which can be seen as well not really on topic but hey that's bad so fair enough.
But then you say no one is allowed to counter it as that would be misleading but the original poster was not.
For the counter to be misleading it would have to be showing something unrelated to the quote being replied to.

I think it was "hey, look, nothing is wrong, look at these FPS scores"

No it was hay look, its like this in eyefinity and it was in reply to Notty and not the thread which is obvious accept it seems to you both as its obvious it does not show micro strutting.

I made it clear in my post, it was a multi-gpu issue. It's obviously a driver issue. Get over the minutia of intent. This is not a court room. SLI or Crossfire is not to be judged by scaling % results alone, that's what those graphs showed. It showed obvious surging, that was all.

I agree.

Hmm, it is interesting that Skyrim was used for this test.
I would like to see this test for Oblivion, Fallout 3 and Fallout: New Vegas as well.
I know that the gamebryo and creation engines have some sort of stutter caused when you move the camera around or move your character and can be fixed with the stutter remover mods for each game (all those games listed above have that stutter).

This video is incorrect and so is TechReport, although I'm not surprised in the dishonesty in reporting or propogating it. Skyrim has a vsync option by default (called iPresentInterval=0 in the SkyrimPrefs.ini file). The Creation engine really depends on this and some pretty funky glitches happen if you turn it off and get high FPS. TechReport clearly turned this off since their cards are getting over 60FPS with a 69FPS average on the 7950 and 74FPS average on the GTX 660Ti. So not only are people trying to prove a point with only a single game, but what they're actually using is TechReport breaking the game and then providing dishonestly presented data.

So the 660TI should display more graphical glitches because they are running at even higher FPS than the 7950?

I'm not sure why disabling v-sync for both would make a comparison invalid.

"The iPresentInterval variable causes the game to "smooth" the interval between displayed frames. If you set it to 0, frames will run as fast as possible, making the game appear to run faster and stutter less. But this is 100% guaranteed to cause problems.

The reason problems happen is that Bethesda's games use animation frames as timers. Scripts run every frame, and most events are not timed on the basis of elapsed time but on the basis of elapsed frames. The iPresentInterval variable introduces a delay to make the execution time of each frame appear more consistent, so that frames in which a lot of script code runs take about the same amount of time to run as those in which little or no script code runs.

Setting iPresentInterval to 0 caused similar bugs in Fallout3 and Oblivion. Doing that fixed the "microstutter" problems and made the game appear smoother, but it caused scripted events to go out of synch with animations. The most obvious effect was that dialogue was no longer lip-synched; the longer a NPC spoke, the more out-of-synch their face became with their speech. But more serious problems would eventually occur."

------------------------------------------

This is news to me but i never messed with this option..

ps. There's actually mods for Fallout3/NV & skyrim to remove microstutter without messing up the game. lol?
