  1. Actually when Chrome enabled site isolation to address the Spectre/Meltdown issues the browser can use as much as 30% more RAM in some cases and typically around 15% more. Chrome has been known for awhile now as being a resource hog and yet I would say most browsers are not very lean these days. Thing is that if you have a older or slower PC your going to notice these slowdowns more. People on Mac’s and Chromebooks complain as well so this isn’t just a Windows Chrome problem. You can try a ad blocker that will give you the perception that Chrome is faster because it has less content to load. Obviously some older PC’s have weaker graphic chips so turning off hardware acceleration might actually benefit in certain cases.
