Question / Help Recording Lag Issue, Settings Irrelevant, Shadowplay Works Fine???

Having a huge issue with lag in my recordings and preview screen. I've tried a variety of different settings with no distinguishable differences. My gameplay runs completely smooth at a steady 90+ FPS but my recording comes out choppy, as in the video below. I've tried using Vsync in game to lock the frames, I've tried changing in game settings, recording settings, resolution, bit rate, encoders, nothing seems to make it go away.

I also attempted to use ShadowPlay by Nvidia to record the same footage, and came away with a much smoother result. I like OBS a lot and wish to keep using it but I'm at wit's end here and I can't have choppy footage going up on my channel. You can see a little stutter in the Shadowplay footage at the start, but nowhere near as noticeable.

My goal is to record in 1080p, preferably at 60fps. It seems more than possible with my setup, but I can't wrap my head around why OBS is producing these choppy results. If anybody else can help me out, I'd greatly appreciate it. I've run out of threads and videos with useful information and it seems like it has to be something specific to my setup.

I think with your 7700k and GTX 1070, you should stick with high settings & 100% render scaling for in-game settings.
Is your 7700k overclocked by chance? This will help a bit as well.
What speed is your RAM running at? 2400Mhz+ will give you the best performance

For a game such as AC Origins (CPU intensive) I would stick with h264 (NVENC) encoding, this will reduce as much load as possible off your CPU.
Using CQP of 15-23, High Performance, High Profile, 0 (Auto) or 2 keyframe Interval will probably be the best bet as well, as AC Origins is also GPU intensive to a large degree.

Make sure to try and reduce the load on your GPU, you want around 15-20fps overhead when using h264 encoder, 10-15fps overhead when using x264 encoder.

If there are any options in-game towards nVidia GameWorks functionality, individually test them to see if one of those are the cause of the issue as well, if it is still stuttering after the above changes and fps limit setting. It may be a case of it putting a lot more load than it seems on your GPU whilst you are recording and playing the game.
I know you have stated in your initial post, however:
Limiting your frame rate in-game will help a lot in getting the best quality out of your hardware in regards to recording/streaming. I recommend using MSI AfterBurner or EVGA Precision to cap your fps to your monitor refresh rate, or 1-3 frames higher than your monitor refresh rate will generally resolve the issue of screen tearing. Try to avoid V-Sync as it can induce input lag.

In your logfile I noticed you have Windows GameDVR enabled. This may be a cause of the performance issue as even when you are not using it, just having it enabled in Windows settings it will always hook into the game process and commit resources (Similar to what OBS does when OBS is open, though more aggressively as it also buffers for replay recording)

Another thing to note, when uploading a logfile to assist in troubleshooting, 3 minutes or more worth of footage is best as it give a lot more frames to be encoded and rendered for output. Generally the best way to do test footage for troubleshooting is to find the most fps intensive area, create a route with that area in the center of it, then run through it, turn around and run through it going the opposite direction back to where you started. It will also assist you in fine-tuning in-game graphic settings.

Last yet not least, it is much easier for others to assist in troubleshooting if you upload the logfile via the menu option in OBS:

I hope this helps!
