because its not an issue of the card itself

its issue on the system/combination of hw/software of some users

No review out there tests for something like this.
thats not true, guru3D did a FCAT review of both 1080 & 1070 and found no stutter whatsoever

I only already linked it here a million times before

well,that's what nvidia says.

my result seem to fall in line with this, my 1080 in comparison to a "healthy 750Ti" from the original post



I did it like 10 times in a row now to be sure and it's always the network driver having the highest DPC

Quote:
nder gaming loads anything below 50us is PERFECT, below 100us is AWESOME, below 200us is OK, above 200us is not OK, anything close and above 500us is a serious problem.

great info, the readings mean little if you don't know how to interpret them. are you sure +100us is OK as long as it's not close to 200us ?

A fix will not make it in time for the next driver so it will likely be included as part of the following driver. If a fix is ready and validated much sooner I will push for a hotfix driver to get it out to everyone as soon as possible.
well that means a hotfix could be here any day, even before any beta driver.

Like you said, it depends.

My system doesn't go above 50 us except for ndis.sys going all the way to 150 us occasionally. What does that mean? Absolutely nothing.

150us is the top end of what is considered "Acceptable" on max loads like gaming, 50-80 us should be the standard @ max load.

Running high loads on your system will linearly increase DPC latency, so the best you can do is try to reduce the DPC Interrupts as much as you can on idle so when facing heavy loads your DPC interrupts will stay in a healthy range.

Aim for less than 30us, use the "Driver" tab of Latencymon to see which processes are taking up the highest DPC executions, after you're done optimizing your system Nvidia's nvlddmkm.sys should be the last (Unfixable) source of DPC lag.

My network driver almost doubles the dpc execution,which you say is the most important one. Should I look for a solution ? use a pci network card instead of onboard ?

because most the reviews were hand selected by nvidea or given there cards for review purposes so there bound to be biased as there not going to bite the hand that feeds them.

they only did gaming reviews/benchmarks. mine have zero problems with gaming. I'm only experiencing the issue on spotify/when gpu is at idle. I can hear the occasional pops on my a5+'s my 970 never had this issue.

used to love guru3d but havent trusted hilberts reviews for years now.

if they're running their test bench systems with high performance power setting,which is kind of probable if not granted, and they did gaming tests instead of listening to music I'd find it probable they did not see this.


about G3D, I see they use two monitors, namely

Dell 3007WFP - QHD up to 2560x1600
ASUS PQ321 native 4K UHD Monitor at 3840 x 2160

for their tests. I don't suppose they optimize the settings and use vsync, they just max out every slider and let it run with vsync off, which I always found to produce minimal hitching and stutter. that paired with what I just wrote above makes it really hard.

the question for me is not about the reviews, it's whether nvidia themselves knew about this and went on with the launch regardless, without even blinking an eye. the answer is that they probably did.
