@Ashpool said in What gaming OS to install on PI 5?:
any specific reason to use the 64 bit instead of the 32 bit one?
With the new RaspiOS, the 64bit variant is recommended by the RPI folks for both Pi4 and Pi5. Furthermore, Pi5 cannot run a 32bit kernel so you'd end up with a 64bit kernel and 32bit OS/userland, which will
cause confusion for source installation, since most emulators/ports assume that if the kernel is 64bit, the OS is also. As a consequence, some source installations will outright fail since they compile for aarch64 (64bit ARM), but that won't work since 64bit dependencies are not installed.
break the installation of kernel modules, because dkms doesn't know how to handle 64bit kernel modules on a 32bit OS.
TL;DR - if you have a Pi5, 64 bit is the recommended OS.
