Hi OCN community!

Mobo: Gigabyte GA-Z170X-GAMING 7 rev 1.0 with BIOS F21
CPU: Intel i7 6700k
RAM: G.Skill F4-3200C15D-16GTZ
PSU: Corsair Professional Series HX650 Bronze Certified
GPU: Gigabyte G1 980 Ti Windforce
SSD: Samsung 850 Evo 500GB
OS: Windows 8.1 64-bit
Monitor: ASUS VG248QE 24" connected via displayport
2nd Monitor: Acer P216HV connected via DVI

I believe I am experiencing micro stuttering as some may call it. I would say that the issue is rare, but very noticeable. Frankly, it looks like this here https://www.youtube.com/watch?v=R1jlWNBmQ7A

I have been coming here to get help on this issue, but so far I have not been able to pin point exactly where the problem is yet and I have done a few things already to try to locate the source of the problem. Hopefully, someone can give me some direction. I made a thread a few days ago, and everyone in that thread agreed my GPU was fine. On top of that I swapped out with another GPU and am still getting the same problems.

I thought my problem might be network related because I was technically experiencing it while playing online games. I was wrong, because I noticed the stuttering in unigine valley benchmark, with the old and new GPU.

Passed 10 tests for memtest86 with no errors. Ran HCI memtest until 1000%. I know my RAM is not in the "tested compatibility" list as per RAM and motherboard manufacturer. But I was told it wouldn't be a big issue.

I have the latest chipset drivers, motherboard bios, and gpu driver. I did a clean install of windows 8.1 64-bit

Someone tried to help me determine if it was hardware or software related. And we were doing tests on my old Samsung 830 128GB. I just replaced the SSD with an 850 Evo. With the Samsung 830, there were a lot of stuttering on the first pass of unigine valley benchmark; they occurred every 5-20 seconds. But as more passes went through there was less stuttering. Almost all the stuttering disappeared after I securely erased the SSD and reinstalled windows.

I am starting to suspect it may be a "dirty" power source from the wall, or faulty motherboard, or faulty PSU. Let me know what you guys think.

Some random facts I experienced:
Yesterday, I couldn't get my on-board sound to work. It stopped working properly after I downgraded the BIOS from F8 to F6. I never had a huge issue with the on-board sound with any BIOS from F5 to F8. I thought there was zero sound, but I noticed the green bar fluctuating on the playback window which indicated that sound was being processed; I found out the sound was technically working because I could hear distorted sounds at the highest volume when I was testing it. I tried flashing back to F8 through the BIOS and then reinstalling windows. Nothing worked, until I flashed the BIOS to the latest at F21, which I regret, because you can't revert back.

I also get this weird stutter in L4D2 when I hit space bar to jump. However, It doesn't happen every time. My L4D2 game stutters once about every 20 jumps I make in-game. I want to say I started having this issue when I got my new keyboard, but it is hard to recall now. I noticed the jumping stutters almost disappeared when I flashed from BIOS F8 to F6.

P.S. I'm very sad, because I really wish I knew what to do at this point. There are some other things I want to mention, but I will let the more experienced people try to evaluate what is going on at this point. I am willing to try anything, but I might have to do a bit of learning along the way. Such as buying a multi-meter and testing rails on the PSU.
 
Some people reported stutter if they were using monitor software that dims the screen depending on the light conditions of the room. Disable that for your monitor and see what happens.

Are you referring to downloaded software for my monitor? I don't have anything like that downloaded. I'm using an ASUS VG248QE 24"
 
Not sure, maybe it's something with your monitor settings. See if there is anything to do with diming (suppose to reduce eye strain) or something like that.
 
1. If you are using f.lux (that is what I was trying to get at) turn on safe mode if you are using it.

2. Set NVIDIA Control Panel to full performance - 1 pre-rendered frame.

No i'm not using f.lux. I don't even know what that is.

I'll try setting to full performance

p.s. is it normal for no load limit to show 1 in afterburner, while i'm gaming? It also moves with voltage limit = 0
 
I was also going to recommend setting to full performance in nVidia Control Panel, you can either do it globally, or per game:
Nvidia CP> Manage 3D Settings>Global/Program Settings>Power Management Mode
Also, head to Windows' Power Options, and set the Power Plan to High Performance mode, just to rule out a problem with that, maybe even disable any Power Saving Features within the BIOS, just for the time being.

I've been running into a similar issue, since around a month ago or so, I'm uncertain whether they coincide with using a newer driver, but when switching to my old SSD which still has the same game on it and running 359.06, there were zero issues, so I was able to rule out a hardware issue at least.
This leaves driver corruptions or issues, I've yet to revert nVidia drivers from my current 378.57, and also backup my current game folder and directly port the working version over to the current one, to rule that out. I only have the issue with one game that I'm aware of, but I've just not tested others as it's the only one I currently play.

Using MSI AfterBurner, GPU-Z, HWInfo, I can see my CPU and GPU usage both drop to 0 when my stuttering occurs.

I'll figure out my issue, but thought I'd let you know what else to look for and see if it helps you out. I understand you've done a fresh install of Windows, but if the games installation remains the same, and the drivers remain the same, albeit reinstalling, then maybe you can slowly eliminate them, one by one.

Not that it should matter, but I'm also running dual monitors, main via DP, secondary via HDMI with the same GPU, even if different OS/CPU etc, we share that in common at least.

Thanks for the replies guys, and the helpful info you provided.

I made a white arrow of where i noticed the correlation of the micro stutter. This happened randomly while playing KF2.

Please correct me if I'm wrong, the voltage limit = 0 and 'No load limit' = 1, shows that GPU did not see anything intensive to process. In addition, frame time reached 200ms, which is common to see for a micro stutter. This just shows evidence of a micro stutter happening, correct? But now I need to find what caused the GPU to relax.

Could this happen because of a bad power cable from PSU or monitor? If so, can I test this with a multi meter? And could this also be a subtle indication of a bad power source from the wall outlet? Today, I bought some tools for testing my wall outlet; should be arriving today from amazon. Might be a waste of money, but I am going to keep the tools anyway, because I sometimes find myself needing them in any given year.

There also seems to be 2 different types of micro stuttering I am observing. But both have a correlation with increased Frame time. The 1st one is shown in the graph above. The 2nd type is only noticed by the increased Frame time, and this one is typically seen when I alt tab back into a game and then the stutter shows up maybe 30 seconds later. After that it seems to be ok. And this reminds me of when I did the unigine valley test with the Samsung 830; I was getting lots of stutters at the start, but as the benchmark did more loops the stutters became less frequent.
 
Are you running any Anti Virus programs? Disable it and see if that makes a difference.

I would roll back a driver release or two. You could also try enabling vsync, which sometimes helps.

EDIT: Check your temps too. Make sure your GPU fan is turning on under load. Thermal throttling can for sure cause this issue.

Roll back a driver for what component? I have a few intel chipset drivers I install. It is not thermal throttling because the temps are fine. I had a few threads I made a couple weeks ago here where I was told to do that.

Edit: The max temp I've seen in AF was 71-72 while running unigine valley. The cap for max temp shown in AF is 75 degrees. Is that max temp for the AF software, or my graphics card?
