Stream speeding up then slowing down back and forth? And regularly skipping a frame?

[Leave3D]

Looking at my stream on Twitch doesn't look like a mess per se, but it does look very abnormal.

I'm new to OBS as I've just switched from using SLOBS for 1.5 years so any help is very appreciated!

Log file should show as attached.
