Yeah it's basically browser fingerprinting (incl. GPU fingerprinting, hence the slowdown) plus google cookie.

If your browser is standard (AKA no anti-fingerprinting plugins) and your advertising cookies are not blocked (privacy or adblocker plugins) you'll probably pass with no issues.

If either of those is not true, you have to solve a bunch of image captchas.

Mouse/keyboard input analysis was just marketing talk; at least when they first released the nocaptcha it wasn't even captured.
