High Usage whenever game is open

Whenever I open a game with VCam open it usage seems to spike no matter if I am using CPU or GPU. But whenever I am out of a game and still streaming then it seems to be fine.

Out of game with OBS open and VCam been captured as a Video Capture Source 17.9%
With a game open like FFXIV or Control with OBS it spikes up to 30-40%

The only effect I am using is the blur at 11.

is this normal or some kind of bug I am running into?

CPU: Ryzen 7 3700X
GPU: RTX 2070 Super (8GB)
