Brave Browser Helper (Renderer) - 100% of CPU

Well, I don’t have Grammerly installed, nor am I using Hardware Acceleration, yet the browser is using 2 GBs and GPU Process is eating up 5.2 GBs of RAM, and I’m not even playing any videos, and just refreshed Brave. Why so much RAM eaten up? Oh, and just between those two, it’s CPU usage is fluctuating between 22% and 60% !!
