Technical Breakdown

Kingdom Hearts is developed with the Luminous Engine, which is known for its heavy utilization of DirectX 11 and 12-based graphics rendering techniques. ROG Ally, on the other hand, utilizes the ARM Mali-G76 GPU, which does not natively support DirectX. As a result, the game’s engine is unable to render graphics efficiently, leading to compatibility issues.

Performance Insights

Furthermore, Kingdom Hearts requires a minimum of 2GB of dedicated video memory for optimal performance. ROG Ally’s integrated GPU only has 1GB of shared memory, which can result in severe performance degradation and graphical artifacts. Additionally, the device’s low-power CPU may struggle to handle the game’s computational demands, leading to stuttering and frame drops.

Technical Analysis

In summary, the technical incompatibilities between Kingdom Hearts' DirectX-based rendering engine and ROG Ally’s ARM Mali-G76 GPU, as well as the device’s limited video memory and CPU capabilities, prevent the game from running effectively on the device. Emulation software, which can translate DirectX calls to ARM-compatible instructions, may provide a workaround but could introduce additional performance issues.
