Green Tunnel in Abeyance causing OBS performance issues

Clip: https://www.twitch.tv/videos/2251507423

Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz

NVIDIA GeForce RTX 2070 SUPER
32gb DDR4 ram

Windows 10 64bit

Concurrently running: Nightingale, OBS, Warudo, Elgato Streamdeck, Streamerbot

While streaming, entering the tunnel in B5 of Abeyance, OBS stuttered and significantly slowed. Nightingale continued running normally, and my CPU/GPU/Memory performance remained consistent in the Task Manager.

When I left the tunnel, OBS stablised. I re-entered the tunnel a number of times, and each time, OBS' performance dropped.

Please see the above clip.

SN: The game and OBS ran without issue for the entirety of the stream except for this specific point.
