This issue I'm guessing is related to verticle sync, screen-tearing, etcetera. It's peculiar and I I'm fairly certain it isn't normal. It looks like dropped framerate. In fullscreen with vsync it isn't an issue so far as I've observed most of the time, outside of that I get a lot of screen tearing (it's completely horrendous in TF2 and oblivion). Framerate locking fixes nothing and may even make it worse.

It is observable in pretty much everything I've tried so far, but I'll list them off and try to post videos.

SOMA - Very noticeable. It's triggered quite frequently and vsync doesn't seem to work at all in windowed mode unfortunately.

Insurgency - Noticeable. Some maps seem to make it more apparent than others, it is an issue regardless of being in windowed mode or not I think. Vsync fixes it somewhat, though it makes my mouse movement seem jittery I think. For some reason nvidia enabled vsync doesn't actually work for this game even in fullscreen. Only the game's own vsync works at all. Dunno if that's normal.

Alien Isolation - Somewhat noticeable. It had a few problem areas when I tested but they were not super huge unless you're watching for them. Might be worse with more testing. Vysnc fixes it in or out of windowed mode.

Dark Souls III - Works fine, anything I could do to disable vsync would probably get me banned anyway. However the screen flashes a lot when starting it up and I don't remember if that's normal or not but it seemed a little excessive.

Skyrim/Fallout 4 - Observable if I do unlock the framerate. Nothing seems to fix it when I try this. Unfortunate, given that doing this and locking the framerate manually is supposed to improve things, so I gather.

TF2 - Insane screen tearing. Heavy frame drops if windowed but screen tearing stops. Borderless windowed mode is a common method for improving performance and convenient for when the game is loading and it borks the overlay. Shame.

Oblivion - Ultimate screen tearing. Without vsync this is unplayable, windowed or not. Definitely exibits the problem as well.

Eldrich - Idunno about the issues I've been going after specifically here but I'm getting stuttering, which IS registering in the OSD. I'm pretty sure that shouldn't be happening.

Witcher - Issue appears to be present and is lessened by vsync, whether it's windowed or full screen. Game stutters a lot no matter what.

Witcher 2 - Issue is present unless vsync is active. Mouse movement seems jittery but using a controller makes movement fairly smooth.

Another issue I cannot figure out is that using afterburner's own recorder causes the GPU power usage to fluctuate and the framerate to go all over the place, regardless of settings. It also never actually recorded anything.

Steps I've taken:
1. Removing Afterburner/Rivatuner
2. Reinstalling drivers
3. Reinstalling drivers after using Device Driver Uninstaller to remove them
4. Reinstalling Windows and doing the above
5. Updating GPU BIOS
6. Simply watching the heat and controlling the fans with afterburner. It has always maintained under 50 degrees.
7. I tried clean boot and underclocking with afterburner. It felt like it worked at first but I think it just made the issue manifest in different areas and different times.
8. I tried swapping slots on the motherboard. Problem still persists.
9. Disabled that xbox dvr thing in regedit

I have, it doesn't make a difference. Idunno, what I primarily find strange is that the FPS counter doesn't catch it. I might try testing at lower refresh rates than 60 to see if that changes anything. I've also cleaned up my original post with new info.

I just picked up the same video card, EVGA GTX 1070 FTW, and I'm running a similar setup. Wish I could say I had a solution for you, but I wanted to say I am running into the same problem. Whenever I play certain FPS' games I get FPS jitter but the FPS counter seems to never dip below 100. I'm wondering if this is an issue with the memory on the card. I'll keep searching for a solution and post back here if I find anything.
