Lagging camera

Hi, im new to meld. Using the virtual camera from meld to only stream on tiktok studio, streaming gaming content, the game is perfect but my face camera is very laggy. In the drop down menu for the camera it only gives me an option of 30fps. When I stream directly through tiktok live studio i dont have this issue buy would like to use meld for yt and or twitch streams. I did notice that it would only happen when in game, so when the pc is using more of the cpu. Hopefully someone knows an easy fix
