Frameskipping / small stutter in games.

Hello! First of all I'd like to say that I've searched the forums for a few days for my specific issue and I've found some threads with some marked as solved and some not. I have tried most of these solutions and it haven't fixed my issues.

The problem I'm having is that the games I play seem to have frame skipping in them. If I'm looking at the one side of the screen while moving forward for instance, the terrain / picture is smooth but will constantly jitter a little bit, like a small stutter but without a frame rate drop (at least it's not noticeable by my eyes nor on a frame rate monitoring software). I really have no idea what's causing this and would love some insight / help.

Specs
CPU - i7 7820x (currently overclocked at 4.5ghz from 3.6 standard. I have tried with the default bios settings as well it doesn't help, temps are fine and Vcore is at 1.25.
GPU - Gtx 1080 founders edition - not overclocked
Motherboard - MSI x299 Tomahawk
RAM - Corsair LPX Vengeance 3000mhz 16gb (2x8) XMP profile enabled.
CPU cooler - Corsair h100i v2 (Also running with the corsair LINK app to monitor the fan / pump)
Main display - Benq XL2410T 120hz
Second display - Benq G2420HDB 60hz
PSU - Corsair RM750x
HDD's - 1TB Seagate ST3000 that's running only games atm and Samsung SSD 850 EVO 250gb that's running windows, drivers and software (like corsair link, hwinfo, CPU-z and gpu drivers).

Things I have tried so far
Resetting the bios to factory settings with CMOS reset button, doesn't help.
Disabled the Intel boost tech and the Boost 3.0, helped with a lot of stuttering issues but frame skipping is still a problem.
Disabled Speedstep and c1 states, doesn't help
Setting windows power plan to high performance, unparking cores and setting cpu minimum affinity to 100%, doesn't help
Uninstalling Corsair LINK software, doesn't help
 
Solution
Ok. Next idea since you have the option, what about trying the 60hz monitor to see what happens. The options you mention on the 120 one shouldn't cause the issue.

Oh crap! Sorry, I forgot to mention it. Yes BIOS is upgraded to the latest version. So far it occurs across all games I've tried.
My OS is also a completely fresh install. Windows 10.

 
When you mention your monitors, what settings are you using? Which are you gaming with? Do you have V-sync enabled, or possible it's tearing? Nothing in your specs should be causing a slowdown, as they are all high performance parts. That said, you seem to be running dual-channel memory kit instead of the quad-channel X299 is designed for.

Not sure about everything you asked me here but I'll do my best answering :D!
The settings on the monitors are standard, I have adjusted colours but that's about it. I use the XL2410T to game on and the other 60hz benq to browse the web, youtube, twitch etc. None of which are running when I am gaming now that I'm testing out stuff for the frame skipping / stuttering. V-sync is disabled, both in-game and through Nvidia control panel. My main game is Cs:Go and I would never want V-sync in that game. Some very small instances of tearing occur but it's quite rare and does not seem related to the frame skipping (at least not to me, correct me if I'm wrong). If by dual channel you mean only 2 RAM sticks (I am a bit unfamilliar with all this tech stuff :)) then yes. I do however have them slotted in the way my motherboard advises me to as my CPU supports 4-channel architecture, which means they are sitting in slots C1 and A1 as it says in my mobo manual instead of C1 and D1 for a 2-channel architecture CPU.

 
OK. I was just checking you were using the 120Hz screen. Are there any "gaming" features of the monitor enabled by default? These could cause an issue I suppose. You tried other GPU driver sets? The quad-channel shouldn't really cause this issue, its just that you lose one of the advantages of the platform itself. Nice system BTW :) If you enable V-sync to test, does the issue still occur up the the 120Hz limit?

Looking at the monitor interface it doesn't look like it. There's PBP (Picture by Picture) which is disabled since I don't use a setup like that anyway. Then there is instant mode which is enabled (I don't really know what this does but it sounds good :D). also something called AMA which I guess has to do with how the monitor handles motion blur? Picture is smoother anyways when I move the mouse around objects in-game fast with it on than with it off. That's about it.
V-Sync didn't really fix the frame skipping issue where the picture seems to stutter without frame rate drops unfortunately.
However when I'm moving around in a game the picture does move a lot smoother with V-Sync on than off, and no tearing at all. I suppose that's what I get though with the introduction of input lag (Oh how I could rant about input lag for days). It's smooth enough without V-Sync that I'd take the extra frame rates and no input lag any day of the week.

Thank you! The setup on paper is cool indeed. Expensive, if not a bit too much but cool nonetheless. :)

It's the same on the 60hz monitor but it screen tears A LOT more.

Okay so I actually managed to fix it. Holy moly I am almost laughing at the solution after all these hours I have spent trying to sort this matter out. Turns out I had to set the multi-display/mixed gpu acceleration in Nvidia control panel to "single display performance". Now I had to rollback a few months worth of drivers to get this option as they for some reason (WHYYYY Nvidia? MORE OPTIONS = MORE POWER) in their newer driver versions. I had tried to rollback earlier but not quite this far. Now, if I update my drivers I suppose the issue will become apparent again... So it's really only a fix for the time being, but oh well. Everything works gloriously now and I can be on point shooting heads off in counter-strike again :D.
1LiquidPC and rarog, thanks for taking your time helping me out, much appreciated!

The driver in which this option was removed if anyone is wondering is WHQL 384.76. So anything prior to that will have that option.
EDIT: Marked the last comment by another user as the solution because I couldn't find another way to mark the thread as solved.
