Latest Nvidia driver high DPC latency?

[Gunbuster]

Is anyone else getting DPC latency spikes with the latest Nvidia driver? I'm in windows 7 64 bit and DPC is spiking up when I mouse over the task bar among other things.

Audio crackle makes me a sad panda, get it together and fix this Nvidia...

What problems are you having? What hardware and what driver?

GA-EP45-UD3P and a GTX 260

You are blaming audio crackle on your video drivers? You want to elaborate?

 

[Gunbuster]

The video driver is causing high DPC latency. Audio playback does not like that.

Not sure if this is the same problem but I play L4D2, have a GTX 260, and win 7 64 bit. On the 185's it's smooth as silk, on the 190's (191's were particularly bad) you'd start to get these pauses where everything freezes up for a fraction of a second then recovers. It gets slowly worse - I've had pauses lasting 5 seconds! During this time the screen freezes, and the audio loops.

Lots of comments about lag spikes like that in the guru3d forums with those drivers, with lots of people still swearing by the 180 series. Real problem when I want to play L4D2 and BFBC2 which needs newer drivers.

Dude you really need to give more info. Full hardware setup and all driver versions.

I'm inclined to think it's another driver that is causing the problem, because I have no problems with the latest WHQL driver, so it's obioviously something specific to your system.

Because you have no issues it is "obviously" a problem with his system?

Wanna explain the logic behind that reasoning one more time?

When I use to use a Nvidia video card I had the same problem but with different games. I don't play L4D2 or BFBC2. Went to ATI and never looked back. Been a lot better sense. Didn't feel like waiting for nvidia to straighten out there new drivers. I been waiting well over a year.

Rofl. Well lets see in what many other ways I can say this.

Isolated to his platform?
Related to his configuration?
Not a widespread issue?

I cant think of any other. What's certain is that if everybody who has the 196.21 WHQL drivers installed had this issue, there would be riots happening. So "obviously" it's a problem specific to his system. You want to get into the semantics of English now?

I was asking if anyone else is having the problem and a link to the DPC latency checker is in the original post...

Jag do you need help interpreting the "semantics" of what "latest drivers" means. (196.21)

Dude, "latest" means nothing in the programming world. Latest can be completely subjective as to what a person thinks is latest, and what actually is latest. When I go on the nvidia site, drivers are labelled with a number and not with "latest".

I'm trying to help you, and you still haven't provided any information that is relevant to fix your problem. Learn how to ask for help before you do.

first I've heard of this, I've been running a pair of GTX 260's for about 6 months now with no issues with audio cracking.

I'm going to have to agree with jag here and say this is an isolated incident and... I wouldn't argue with people trying to help, it's not a good way to continue to get free help. But the last time I remember having this issue my speaker cord was touching or close to both the power cord going to the computer, the monitor video and power cable. i untangled the mess and it went away...

I have discovered various forum posts on this around the web with no apparent solutions.

i have a samsung r580 notebook running windows 7 (32).

DCP shows various latency spikes which are causing stuttering in ableton live.

i managed to isolate the problem to the nvidia graphics drivers by uninstalling them. when running on the windows vga drivers there is no latency whatsoever. this leaves my with working audio but useless video...

i have now tried all supported drivers listed on the nvidia website (a total of 3) and the only ones that are on the samsung support page, to no avail.

i notice that you mention earlier drivers may not have these problems - is it possible to get earlier drivers that are supported by the 310m notebook series? nvidia page only lists 3...

I think it's more of a motherboard problem. Gigabyte boards generally show higher DPC latency than competitors. The issue seems to be *almost* gone now. Especially with P55/X58 boards on Intel side. This was most prevalent with gigabyte's LGA775 boards.

I have had problem with mine as well since day 1, so I don't think it's ForceWare's fault. (Though I haven't used an AMD card on mine) Thankfully the visible symptom (usually a brief skipping while playing music/video/games) doesn't occur too often, so I just ignore it. Of course if you were to leave the DPC Latency check tool you'll see it all the time but that's just a tool, not an actual app for any productivity or entertainment, so my suggestion is to simply ignore it.

Wow I didn't realize this thread was a necro'ed one.
