Hello @zany130, can you identify what threads are using more resources than you expected? See https://github.com/ValveSoftware/steam-for-linux/issues/7372#issuecomment-696193644 for some instructions on collecting that kind of info.

it just says its /home/zany130/.local/share/Steam/ubuntu12_32/steam
