Third design flaw to hit the GeForce GTX 1080 and GTX 1070

[3DVagabond]

I guess running out of spec is something AMD users are happy with, what with AMDs latest flop overvolting on the PCIe bus.
There is nothing wrong with 10xx series DVI port..It runs in spec completely stable.
End of story....

A bit off topic?

It's about the 10 series. People just want to deflect with other things.

"If I disable the GTX 1080 in the device manager, the DPC latency goes back to 20-25us. I can watch a video on youtube or Netflix and the DPC doesn't change and I don't experience stutter or crackling sound. As soon as I enable the graphics card driver again, the DPC goes back to 350-400us, and it's a stutter fest when I watch videos or play games. On my side, with LatencyMon, it shows 350us when idle and when In game, it spikes up to 1500us with nvidia driver alone spiking at 1200us."

"Well, today I had a chance to spend a bit of more time investigating the issue. I managed to use another computer of mine that I use as a server that needed a bit of maintenance (a good old HP Z400 I got for cheap at my job). And guess what? As soon as I started this HP Z400 with the GTX 1080 in, the DPC jumped from 80us to 480-500us.

So unfortunately, I think I ruled out that the gaming computer I have is the issue. And I cannot really RMA the GPU because the DPC is high. I am quite certain that switching it to a brand new one won't fix the issue as I am pretty sure that the Hardware is not the root cause here, but the drivers are. 3-4 years ago, I had DPC issues with the Asus Xonar DX sound card, and switching the drivers to third party low dpc ones fixed the DPC issue.
So I just hope that Nvidia takes the time to look at this, even though my expectations are quite low to be frank."

"Yes in LatencyMon the Nvidia driver goes from like .03 ms highest execution time to like .9+ ms right away under load."

"I'm having this issue as well: high DPC latency that is causing microstutter. Tested with both LatencyMon and DPC Latency Checker. I did a fresh install and ONLY installed Nvidia drivers. LatencyMon Flags the Nvidia driver as the culprit and at each DPC latency spike I get microstutter in game. This does NOT happen with the integrated GPU (note that I disable the integrated GPU when running the Nvidia card, but for kicks I also left it enabled to see if there was a difference and there was not).

It's not OS dependent. I've tested on Windows 7, 8, 8.1, and 10. Also my ONLY hardware change was the 1080, from a Titan X.

Specs:
i7 6700K @ stock
Gigabyte Z170x Gaming 7
GTX 1080 Founder's Edition
16GB Corsair Vengeance DDR4 RAM @ 2333MHz
Corsair HX 1000 PSU
Samsung Pro 850 1TB SSD

Bios settings changed:
Fast Boot: Diabled > Ultra Fast Boot
DDR4 RAM: Auto > XMP Profile 1
Integrated GPU: Enabled > Disabled

Everything else is stock."

"1st of all, the audio and fps drops don't occur every 20 minutes, they occur every 10 seconds. This makes games unplayable, videos unwatchable, music unable to listen to, so it's more than a "hitch." This makes my computer unusable for what I need it to do."

"ts a driver issue. i have the same fun in CS:GO at 450fps at 144hz. Really frustrating to have such a good card, such high fps but yet experience harsh microstutter. Im on windows 10 and dpc latency checker is glitching, always stays at 1000 min. Latency Monitor on the other hand gives me correct results. Having the machine AFK, not even moving the mouse, the latency is fine and everything is green, until i open a window, chrome, literally anything, the latency spikes into the orange area.

I reinstalled windows, have literally no drivers installed. Being in a 4k$ build this really hurts, hope nvidia fixes their shit."

"I have the same issue."

"I just recently started watching Netflix videos on my system (GTX 1080), and in high definition full screen they stutter in video and audio, as soon as I exit the full screen mode they are fine again. Happens on both the Netflix Windows 10 app and Microsoft Edge. It's bad enough that I can't use the full screen mode."

Does it impact gaming? Damn, this video looks like the game is unplayable on a $800 GPU...
