I always will have 20 to 50 web browser windows open as well as many tabs in each of those windows.
The main issue I was encountering, and my best guess, from a lot of testing over the past three years, is related to the large pixel count of my desktop - I would frequently encounter 1 to 2 seconds of lag/unresponsiveness when switching from chrome to another (chrome) application in the background. As this has been a nearly 3 year long issue, I’ve tried many , MANY fixes/work arounds The two most impactful were upgrading from windows 10 to windows 11. And switching from chrome from primarily using chrome to Firefox. (The issue was actually the same with chrome canary, as well as with GPU rendering enabled or disabled in each browser.)
while I now run Firefox 24/7, I will occasionally open up chrome or chrome canary in unique use cases, and still notice the performance improvement in firefox during those times.
(to be clear when I say I’ve tried and tested just about everything, I mean it from fresh new iOS installs with no applications, except chrome, two upgrading every piece of hardware a few times over) - the issue persisted.I even do some design work so it's honestly pretty bad.
