Question / Help Choppy FPS in recordings (NVENC), however smooth in Shadowplay

Hello
I've tried so many different settings but the result is always the same.
I'm trying to record BF4 footage, in game its smooth 100~ FPS. FPS Loss: With Shadowplay I'm losing about 5 FPS, with OBS about 10 FPS. I don't care either way because I'm still going over 80 FPS at all times.
With Shadowplay the footage is smooth but with OBS there's is some choppiness. My best description is that the result looks like the game was running at 45-60 FPS while recording.

I'm using the NVENC Encoder in OBS, 1920x1200 with no scaling. Using a 6600K with a GTX970 and 16GB RAM.
I have tried CBR with 50k bitrate and all the way down to 30k bitrate. Also tried VBR with the same bitrate and even tried CQP with values of 16-18-20. Preset- I tried Default or High Quality. Profile- I tried High or Main. Two pass encoding- I tried with and without. B-Frames- I tried 0, 2, 3 and 4.
Also in Video options, 60 FPS and Lanczos, however I tried 59.94 FPS and Bilinear\Bicubic but to no avail.

Checking the logs of my recordings, looks like there are "lagged frames due to rendering lag/stalls" ranging from 0.3% and up to 5%. Is this the cause, that I'm losing frames? If so, what is the reason? The thing is, I'm not always losing frames in high GPU\CPU stress conditions, the choppiness even occurs while just running in empty areas.

What baffles me is that using Shadowplay the result is silky smooth, using the same Encoder. I've dropped down and played around with all of the settings, I thought that I would find an option to lose some quality but gain the smooth output that I'm looking for but it didn't happen.

I would appreciate help in this matter.
Thanks in advance,
Daniel.
