Well, it's an issue that is many years old. Another one that i'm reminded of is the power issue with screens at high refresh rates.. that was brought to public attention a while back when 165hz screens were loading a gtx980 to like 150w at idle, they said that'd be fixed in a week and it's still not completely dealt with

This is a really old issue which crops with some version of nvidia drivers. People don't usually get problems or notice them otherwise they wouldn't switch over from AMD.

@Dragon is this stuttering you're experiencing reflected in frametimes jumping like crazy in games ? Or is it just observable with fps/frametime monitoring software not showing any anomallies ?

I can see it while playing, it's intermittent and happens more prominently on Overwatch, the worst Microstuttering happens when my DPC latency reaches 1500-2000us, for a few seconds it is extremely noticeable and annoying.

I'm concerned. Does it cause clown cursor?

I do notice slight stutters in games, I thought it was down to my x34 not keeping up.. but it seems it might be this latency issue

pretty glad ive seen this before I sold the monitor as I was close to doing redface.gif

Guys, have you tried using the Windows Performance Analyzer, as it's very good at pinpointing where DPC latency comes from. What am I talking, it's an excellent tool.

You can download it from here

For Instructions on how to use it you can see this thread - although it's quite a bit old and you do not need to use cmd, you'll get the idea - this link

It looks like this now but as i said, it does the job and you'll see whether it's the GPU driver that causes your issues:


Edit:
The above is my PC logged for 80s (till my DPC Latency Checker shows a spike) which in this case is caused by usbport.sys, but since it's not that bad...I don't care smile.gif

well I've got 1000us,which as you say is bad/terrible compared to less than 100us, but I can't reproduce the issues you're having. Tried it on Far Cry 4 and Witcher 3, with both g-sync or ulmb, max or custom settings, vsync on, fast sync, loading a few videos on youtube at the same time,playing flac files, running just about every piece of software there is on my system, including sensor reading... nothing since yesterday. The only thing I found out is how much stuff can my rig handle flawlessly at the same time.
I think it might be connected to W10 or maybe some driver conflict (guy said he's got 290 in his system too) that is causing this latency to show its bad side. So even though I do see my reading in the yellow zone I'm not gonna try to fix it if it's not broken. If a hotfix from nvidia is up I'll try it to see the readings for sure though.

if you're on Win 8.1 then you should be using Latency Monitor, not the Latency Checker IIRC

just in case
