OmegaMalkior I think one of the reasons that it did it so well was because Legacy Edge let windows do all the hard work, which is why the touchscreen scrolling isn't as good as it was in the last version. Edge probably used windows code that allowed it to prioritize tasks to maximize the frame rate, usually at 60 fps. Even when the frame rate slowed, Edge and Explorer managed to animate things smoothly regardless of how the browser was doing by (I assume) letting windows have control of that task. Trade secrets I assume.

Microsoft said they wont add the code, or whatever sorcery they have to new edge because it has to run on more operating systems than just windows. I'm not sure why they don't just add it exclusively for the windows version and say that it works slightly better on windows, but they have their reasons.
