The massive 125% increase in Bully highlights how some PS2 titles were heavily reliant on VU1, becoming entirely GPU/CPU-bottlenecked without the hack.

| | What It Does | When to Use | | :--- | :--- | :--- | | Enable INTC Spin Detection | Reduces CPU usage by handling a specific PS2 hardware quirk more efficiently. | A safe general speed boost for most games. | | Enable Wait Loop Detection | Identifies and bypasses idle loops in the game's code, freeing up CPU cycles. | Another safe and effective performance enhancer. | | mVU Flag Hack | A more aggressive hack for the microVU recompiler. Can cause graphical errors in some games but helps in others. | As a secondary option if INTC and Wait Loop aren't enough. | | VU Cycle Stealing | Aggressive hack that steals cycles from the EE (Emotion Engine) to give more time to the VUs. Can cause slowdown or lag if set too high. | As a last resort for very demanding games, starting at the lowest setting (e.g., "1"). | | EE Cyclerate | Effectively "underclocks" the emulated PS2's main CPU. Can cause desynchronization issues, especially in audio. | As a final, more destructive option for performance, best to use the minimal setting ("2") if needed. |
