Strange Lag between my Camera and Screen Share (please help!)

[jmurphy0812]

I am experiencing issues with lagging during my Zoom sessions. When streaming my computer desktop and using my 3rd party external webcam. I get what seems like a desync between the two streaming devices. Meaning there is a significant delay and mismatch of the two feeds. 

For example, If I type something or move my mouse on the screenshare, it will take a few seconds before it shows me doing it on a webcam. 

Do you have any idea what could cause this, and has anyone ever experienced this before?
