why this kind of issue was not picked up with the reviews i would have held of if i had known about this

Issues don't get picked up by reviewers because they have say a week to test the card so they run 20 benches on it but never go and play for 2 weeks on it a few games and spending tons of in-game time with the hardware. Obviously these kind of issues only show when you use the product for a longer time not just bench it for a few hours. Also the issue is not making stutter for everyone it's only certain combinations of HW and SW hence it's not easy to replicated 100%, until Nvidia themselves has a system that does this or they have explanation of the issue which they should have now and be looking into the crappy DPC latency for years now, then they could do something about it.

It's similar to why wasn't 840 EVO SSD TLC issue mentioned in reviews, when the issue took 2+ months to start showing up.

Not everyone's system is affected, although I bet the DPC can be seen higher for Nvidia driver than for other drivers installed on all of them.

Totally understand and agree with you

but it does not take more than a couple of mins to find out there is a DPC issue i mean some review sites even run this tool or used too on motherboards

Well :| Just got my Gigabyte 1070 Xtreme Gaming. Noticed some massive stutters in Overwatch and... pretty much every game I tried out. I'm sad lol. *sigh*

EDIT: This is on Idle.

Moving windows and the browser around and I get stutters lol.

just installed my EVGA 1070 last night- 200-250+fps in overwatch, no stuttering to speak of, it was butter smooth on my 144hz monitor, very pleased. Previous card was radeon 7850

Note i'm on win 7.

He is still correct though. Review sites often times use bench rigs that are stripped down systems with the bare bones minimum software and hardware necessary to test. If they happen to have a hardware combination on their bench rig that doesn't have DPC latency issues then you're simply not going to observe these issues.

Tonight I am going to take a screenshot of my DPC latency then I am going to shadowplay a 5 minute clip of me playing CSGO. You will first observe that on the surface I don't have particularly out of control DPC latency but the video will show you the microstutter I am experiencing in game. I literally don't have an explanation for this behavior. Whats even more confusing is that the first two days of me having the 1080 installed were perfectly fine. I didn't have this microstutter, but since then I managed to observe DPC latency spikes which I got rid of again by DDUing my Nvidia drivers and software then re-installing the latest driver. DPC latency spikes gone but the microstutter is still there.

Edit: Oh and I forgot to mention that CSGO is the only damn game I can notice this microstutter in. I played Dying Light like a boss with visual settings cranked @ 1440p and had no problems at all. I also played Thief @ 1440p with visuals cranked and had no problems. This crap makes no sense.

I was agreeing with him and yes he is correct but still ?

I have tested thus far over 8 different pc set-ups now and with 7x 10 series cards i have a 1060 build this weekend so i assume that's going to be the same too

even with 2 pc's stripped down bare min win 7's and bare min hardware i still all similar high DPC with any 10 card

Agree some are worse than others but all the same issue some of the pc's built where even having hard time just browsing with a 10 card

for me personally its a problem as these are & have been used for system builds and does not look good passing them off with these sorts of issues to clients
yes there aware that its being fixed but for the prices being paid for the 10's you would have thought nvidia would have got this right ..

1 chap has returned his pc 4 times now since having his pc for 2 months because of the DPC issue....And what is strange that some 10 cards have higher DPC than others even on the same build

I thought they fixed the previous generations that suffered from this issue, they did not? Wow. I really though they did.

From video it looks to me as if some application is accessing hard drive or the game is loading assets to the GPU or is accessing hard drive or even solid state drive. Similar stuff can also happen when your CPU is overloaded and the scheduler cannot give the game enough CPU time for smooth gameplay, for example when encoding video in background on all cores or some other CPU intensive task. Or antivirus running in background is a total killer and would cause this too at least the old antivirus programs that didn't run only at system idle.
The thing is that she has looked into all that. It happens all the time on overwatch ever since the release and there is no unusual disk access or any other processes taking up resources.
It is really a puzzling problem that only affects some users, which is why I wondered when reading about the DPC issues if that could somehow be the reason.
There is also no such problems in any of her other games and was not a issue with overwatch either back when it was still in beta.
Afaik she has also reinstalled the game, cleared out the save/profile files and tried installing it to another disk and yet the same problem even if you lower the resolution and graphical settings to minimum.

Edit: got some information.. she also tried disabling antivirus, played with the vsync as well as various other settings in nvidia drivers, reinstalled and tried different drivers with a fresh driver install and apparently she even already tried unparking cores..

May seem a daft question but has she tried unplugging the other display ...also swapping displays too I did have system that had strange issues stutters in some games and was down to 2 displays plugged in

That is a interesting question as I know she uses a dual monitor setup, so going to forward that to her and see what happens.
At this point nearly everything else has been ruled out anyways ;P

Edit: already tried unplugging second monitor as well as any usb devices besides keyboard and mouse...
Only thing she has not tried is swapping the monitor themselves, so I will update when she tries that.

Make sure cables get swapped too

What is her full spec?
