Nvidia acknowledge Stutter problem!

Either way, it's an Nvidia specific issue. People are getting it with 6xx series cards too it would seem. A m8 of mine put his 7970 back in and the TDRs went away.

That's what would worry me the most about this stuttering thing, if they don't find a 100% fix or if it turns out to be something that is inherent in the design. We already know that it's related to the dynamic clock feature.

Fair point.

Ah thread is clean :)

I was going to ask this yesterday but feared it might get lost in all the hate...

Can someone just confirm I have this 'stutter' issue so I can rule it out being something else, some titles I play I get a slight frame drop when a fair bit is happening on screen that casuses a kind of slide show effect, it only lasts a few seconds then it evens its self out, I hope that describes it well.

Have you tried the latest Betas bud? 301.24?
 
So drivers ruled out, is this the stutter problem that I'm experiencing?

It seems to happen more in some games (fifa12, Batman AC) then others (BF3). Also it doesn't happen in any benchmarking program such as Heaven or 3dMark11.

Batman AC stuttered like hell in dx11 before being patched, so make sure you are up to date with the patches.

Yeah early on in the games life that issue rendered the game pretty much unplayable in DX11 on 6950 CF. The game is fully patched (via steam). Will try more games today, in both BMAC and Fifa12 they both have an in-game forced frame limit of 60fps not sure if this is linked to the stutter? From looking at the frame rates when this happens it only drops from 60 down to around 54 but it feels like it drops below 10.
 
TDR issue is a complex one and not 100% an nVidia driver issue, its probably not fixed for everyone but probably fixed for some as the triggers for what causes it varies from system to system.

While not seen the stuttering issue myself on any setup, I'd rather nVidia didn't do an AMD and rush out a hotfix that then gets the problems reduced in priority and hence never properly fixed if the hotfix is just a bandaid rather than a solution.

Honestly I thought the problem with most TDR errors with the 560ti series was due to the majority of the cards being non reference and coming in pre OC with an inadequate voltage margin. A driver was released that caused the clocks to be more sensitive to this and bam TDR's all round.

Still do not think Nvidia ever addressed this fully but they did do something with TDR's caused by h/w accelerated browsers and flash video.

I think that they encouraged vendors to release bios updates with a bump in the voltage.

My KFA2 560ti had this but I just used a bios editor to up the voltage margin in 3d mode so that it had a large voltage so that it could use more if needed. The TDR's vanished. You could downclock your card to stock nvidia 560ti clocks to prove that it was the cause.

Though I am pretty sure in a previous driver version it wasn't needed so something must have changed in drivers.

Yeh they kinda fixed it and turned it into a PSOD issue instead :rolleyes::p

301 drivers are a bit of a pain :mad:
 
If you are suffering the stuttering, I could imagine it realy cheesing me off, so do hope it gets fixed for anyone suffering soon. Just seems strange to me, that the games I have played, it is real smooth with no stuttering at all:confused:

Well clearly its not affecting everyone, or else I'm sure the nvidia forums thread would be a lot longer than it is :)
Glad yours is working fine, perhaps it is some kind of conflict with other programs and therefore only affecting some people?

If I can find my Windows7 disc I'm going to do a fresh install later today just to rule this out, it could be quite possible as I have a mountain of crud installed that I never use :p
 
Toms hardware has asked Nvidia about the problem:

'Nvidia Responds to GeForce 600 Series V-Sync Stuttering Issue

Nvidia provides an official response to the reported v-sync stuttering issue with its GeForce GTX 600 Series


Tom's Hardware has received several requests to look into a v-sync issue that a number of owners are seeing with Nvidia's new GeForce GTX 600-series graphics cards. A number of readers have pointed us in the direction of a very long forum thread where multiple customers express concern over stuttering problems with their Kepler-based graphics cards.

Our editorial team played through a number of games with GeForce GTX 600-series board and was unsuccessful in reproducing the issue. As such, we're fairly confident that the issue does not apply to every configuration based on Nvidia's newest cards; some folks are experiencing it, while others aren't.

Eager for an explanation, Tom's Hardware reached out to Nvidia for its response, understanding that owners of $400, $500, and $1000 graphics cards want to know why their boards are misbehaving. The company sent over an official response to the GeForce GTX 600-series stuttering issue, which reads:

We have received reports of an intermittent v-sync stuttering issue from some of our customers. We’ve root caused the issue to a driver bug and identified a fix for it. The fix requires extensive testing though, and will not be available until our next major driver release targeted for June (post-R300). For users experiencing this issue, the interim workaround is to disable v-sync via the Nvidia Control Panel or in-game graphics settings menu.


Although that's not necessarily the most reassuring message, we're at least glad to see that Nvidia has identified the issue and is working on a fix. We'll update you if we hear any more on this, so stay tuned!'

Hopefully Nvidia do get it all sorted out by June.

560 cards seemed to suffer from it badly as well as a subset of the 460s. With the 560s a lot of it probably was caused by voltage issues but it was also triggered on other setups by other factors hence theres no one size fits all fix - althought most of the 560s with that issue would probably be solved by the same fix.
 
I didn't notice at first as I had only been playing BF3 which I've always had some issues with but since seeing this post I have tried many other games and can confirm that I have this issue and am a bit gutted tbh.

Just to chip in to say I have noticed this issue too (predominantly in Fifa 12). I'm on the 301.34 drivers. (GTX670)

I was experimenting with the nvidia control panel settings, and found that having V-sync on adaptive, but tripple buffering off seemed to help quite a bit (but not totally eliminate) the stuttering. I don't know if this was just a fluke, but I was testing it by changing one setting at a time.
 
I'm not sure if this issue is causing it entirely, but I first noticed the stuttering in Skyrim (which has vsync turned on by default). The reason I think its an issue with the 680 (or it's drivers) is because it didn't happen with my previous 580, even at the exact same settings.

It's definitely not performance related, the card is barely breaking a sweat and nor is my CPU. It doesn't happen constantly either, but in short intermittant bursts, as if something in the background is interrupting the flow of frames and hence the stutters. I'd normally blame it on a hard disk loading or texture streaming issue, but since it didn't happen on my 580 I doubt it is that.
