Even if you buy a Chromebook that supports a 120Hz refresh rate, you won’t be able to run games at 120Hz. The Lenovo IdeaPad 5i Gaming Chromebook and Acer Chromebook 516 GE are two gaming-focused Chromebooks with 120Hz screens, but gamers can still only run games at 60Hz due to system limitations.
Most of the core ChromeOS experience runs very smoothly at 120Hz, and some online games run faster, but due to the lack of adaptations for Android apps, Steam games, and Linux virtual machines, these apps can only run locked at 60Hz.
This is because Android applications, Steam games, Linux virtual machines and other such “other” applications are running in the virtual machine. Foreign tech media 9to5Google hopes that the Google ChromeOS team will find a solution that will allow these apps to run smoothly at 120Hz as well.
