I'm not sure if I'm bottlenecking or what.

Sounds like things haven't changed much for you.
Yes, it can occur specifically during gaming sessions.
Lots of times it works well, but when I run Streamlabs, my frames and everything look consistent and tidy as expected—it’s just odd.
See how CPU and GPU are performing—use Task Manager or similar tools.
Using Streamlabs results in roughly 65% CPU usage and similar GPU load.
Without streamlabs, performance is around 55% on the CPU and 45% on the GPU. Still, my CPU usage is higher overall.
Nothing comes to mind for that situation, but I hope another person can assist.
