Unmatched Gaming Performance For games like PUBG Mobile , Free Fire , Call of Duty Mobile , and Genshin Impact (older versions), Prime OS 2.1.3 offered native keyboard mapping (Keymapping) with virtually zero input lag. Because it wasn't running inside Windows, you gained an extra 2-4 GB of RAM and reduced CPU overhead. 2.

File Manager Plus The included file manager allowed you to browse your Windows partitions (C:/ or D:/ drives) directly from Android. This made transferring ROMs, music, or APKs seamless without needing a USB cable.
