I have been having this problem for months and I usually controlled it by limiting the RAM usage in the GX Control.
Fortunately, I found a solution yesterday that worked on my pc and it also decreased the cpu usage but there is no guarantee that it will work for you but it’s worth a try:
- Open flags by using the url chrome://flags
- Search for and enable Hardware-accelerated video decode and Hardware-accelerated video encode
- Switch the Choose ANGLE graphics backend to OpenGL
As you can see in the screenshot below, I have so many tabs open but the RAM or CPU usages haven't sky-rocketed. Before this, the app would have used up 5GB of RAM
