Hi, I had a similar problem. My laptop wasn’t exactly the newest. It turns out the problem is that browser games have become much more demanding these days, putting a lot of strain on computers and laptops. Most likely, your issue is with your laptop. I watched a lot of videos and consulted with experienced people in this field, and I’ve decided to get a new laptop. They say MAC laptops are good for this; if you’re interested, you can check the specs here: https://www.apple.com/mac/. You might also want to take your laptop to a specialist; they might be able to help.
