While the reply is great I feel it is missing the point a bit. The reason it feels so fast is IMO because everything else is so slow. Look at the numbers in below link (near the bottom). Windows 10 is extremely slow. Linux is often twice as fast with the same hardware and the same software. Why they still haven't fixed it is beyond me.

Linux is no different. Gnome terminal has a ton of input latency compared to xterm. It's like night and day. A lot of graphical apps in Linux have added input latency just like Windows. It's due to layers of UI abstractions and frameworks (the same as Windows but different UI toolkits of course).
That links just shows that VSCode and Atom are both horrendously bad for input latency on any OS.
It's noticeably worse than ubuntu.exe in terms of input latency but has better features for screencasts (ie. hotkeys to adjust font sizes).
Last week they released a version that supposedly removes 30ms of latency which sounds very promising, but the author didn't create a Windows installer for it yet.
