Do ATI cards 'stutter'?

Evan with 1 gpu disabled my 8800gtx ran smoother.
I just think that games on an nvidia card seem to run smoother and I havent a clue why? All I can think is that its down to drivers. This also doesn't apply to all games.
+1 here also. Going for a 5870 now which should solve these annoying xfire and micro stutters. I'll also be extremely glad of the lower heat and power consumption!
yes, ATI cards do micro shutter.
5870, playing games such as Crysis, GTA 4 and Far Cry 2 will notice those micro shuttering.
i'll be getting the next nVidia architecture for my new card. 8800GTX, gtx260 never had this kind of problem.
people just look at benchmarkk numbers, that's less than half the story. gaming experience is more about minimal FPS and micro shuttering, that's where nVidia always gives best results.

I very much doubt that your getting micro stutter because when its triggered its a continuous juddering & not a now then pause.
And if that was the case with single ATI cards then people would be sending them back by the truck load.
And 2 of the games you highlight are notorious for putting gfx cards under a lot of strain & with low fps.

it's more of a tiny jitter now and then, in GTA 4, it's a jitter when i spin my mouse around really quick. in Crysis, it's like a jitter every now and then.
the thing is, never had that problem with nVidia in Crysis or GTA4. and that's a gtx260, not a powerful card by any means.
I get (micro)stuttering with GTA IV, I think it's the ****ed up implementation of the console port that is the problem though 
Haven't noticed it with other games though. Hopefully if I decide to get another 5850 in the future, I won't experience these annoying issues. Some people don't even notice it.
My nightmare was tearing that occurred in many games when ran with v-sync off. Fixed it mostly by forcing my monitor with 76Hz refresh rate though

This ^
Microstutter plagued SLI and crossfire setups when they were first released. The problem has since been fixed with drivers. What you seen now are FPS drops because your cards aren't up to sratch. Anyone who argues different has never truely experienced the microstutter that occured on the early SLI and crossfire setups.
Just as i thought a jitter now & then that's not micro stutter that another problem & a problem with your set for what ever reason i have never had that but i see it in videos of games sometimes.

running on a NV card.

it's not as bad as that video.
my point is, i've never noticed anything on nVidia card, but i did notice these on ATI cards. so in my experience, ATI cards is not as good as nVidia cards.
perhaps ATI knows this, hence they are bringing out Southern Island cards with tweaked memory interface to combat this problem. perhaps Southern Island cards will see tiny performance gain from Cypress, but will have butter smooth gameplay.
Sometimes people can also confuse it with something else going on. Doom 3 for example has slight skipping when you are running along a corridor. Next time you play it watch it carefully. It's very subtle, nothing like in that video posted but a subtle twitch is evident, maybe down to the engine, I don't know.
in my experience stuttering, pausing, etc. in crysis is ALL caused by running out of physical memory, have never seen it caused by anything other than that personally. with my system when i had RAM modules fail (reduced to 2Gb) crysis would stutter quite a bit in parts and the console would say my memory was basically maxed out, when i got modules back from repair the stuttering was completely gone, same GPU, same CPU, same settings, therefore the only cause is memory managed to reduce stuttering with lower amount of memory by disabling streaming and other things, but it resulted in longer load-times, etc.
managed to reduce stuttering with lower amount of memory by disabling streaming and other things, but it resulted in longer load-times, etc.In your experience you have had more problems with ATI cards than NV cards, that does not mean that NV cards are better than ATI cards because what does it mean when someone else has more trouble with NV cards than ATI cards, does that mean ATi cards are better than NV cards, that's a total contradiction right there.
I think your using the wrong terms of definition.
As my video showed it happens on both brand so it must be down to other factors than just the card.

I have never noticed proper microstutter on SLI setups - the 7950GX2 was free of any noticeable level of it and nothing I've used since then has been affected by it. There was some issues with the 6800 in SLI but there was more obvious problems than microstutter with SLI back then.

Hhmm interesting. I havn't used dual cards setups since "real SLI" on a pair of voodoos.
One thing I remember from them was what I can only call a shimmering effect. This was due to the method the screen was rendered with, i.e. real sli drew alternate horizontal lines on the image.
No idea what the method is of modern multiple set ups, but maybe the type of rendering used can have an effect.
re stuttering with single cards I would suspect is to do with the way the game is buffered and having vsync on, which can screw the frame rate up if your card doesnt have the necessary grunt.

"Perhaps" is a big word. It would be a very big assumption to think a tweaked memory interface would stop what i perceive to be unsynced cards.
