I'm on a 2019 16" MBP 2.6GHz i7 with a 5300M. This machine isn't a powerhouse, but it can drive 1080p240Hz + 1440p144Hz buttery smooth for a million Firefox tabs and a couple IntelliJ projects (if everything's all indexed...). On this site, I get like 10fps while doing things, clicking, moving around, etc. It doesn't even look like motion. I threw it into Firefox's profiler and it has consistent "janks" between 100ms to over 200ms. No thanks.
