Even with hardware support, Google ChromeOS devices cannot turn on 120Hz in the game.

CTOnews.com, November 23, even if you buy a Chromebook that supports 120Hz refresh rates, you won't be able to run games under 120Hz. Lenovo IdeaPad 5i Gaming Chromebook and Acer Chromebook 516 GE are the Chromebook of the two main games, equipped with 120Hz screens, but players can only run games under 60Hz due to system limitations.

CTOnews.com learned that although most of the core experiences of ChromeOS run smoothly under 120Hz and run some online games faster, due to the lack of adaptation to Android apps, Steam games, and Linux virtual machines, these applications can only be locked under 60Hz.

This is because "other" apps such as Android apps, Steam games, and Linux virtual machines run in virtual machines. Foreign technology media 9to5Google hopes that Google ChromeOS team will find a solution so that these applications can run smoothly under 120Hz.
