Chrome Bring ‘Back Forward Cache’ to Desktop for Instant Page Loads
Back-forward caches provides instantaneous page loading when navigating backward or forward. Devs want to experimentally introduce the feature on all of Chrome’s desktop platforms, i.e. Windows, macOS and Linux, in the upcoming Google Chrome 92 release, but you can still access this feature on latest version of Chrome i.e. v90.0.44.
Regarding this feature Google developer says -
Several options are available here, including experimental support for caching across all pages, or just those on the same site.
