So after several hours of trying to figure out what was causing this. I narrowed it down to Grammarly Extension. With it on, Brave opens up 30 tabs, pegs at 70-80 %. Removing the extension helps, but every once in a while, it will sit and hover at 30-40% CPU usage. So, I am back to chrome for a while. Grammarly is vital to my daily work. I am hoping this can be sorted out. Like I said, it was working fine initially this morning from about 9 am EST till about noonish.
