Offline status applies on any device: it comes from the store's DRM and account rules, not the hardware. These are listed facts, not performance tests. Handheld memory is shared with graphics, so the RAM check only passes when the game's minimum is below the device's RAM. CPU and graphics are not compared. Where device info comes from.
