| Limitation | Impact | |------------|--------| | | Cannot run DirectX games or Aero interface. | | High battery drain | Emulation consumes 2–3× more power than native apps. | | Poor multi-touch support | Right-click and dragging require stylus or external mouse. | | Unstable for high RAM guests | >1 GB RAM on ARM causes memory allocation failures. | | No suspend/resume | VM must be shut down completely on app background. | | Android-specific constraints | No access to /dev/kvm, limited file system access, background process killing. | | Lack of SMP efficiency | Adding cores reduces performance due to TCG lock contention. |
