| Setting Category | Specific Setting | Recommended Value | Explanation | | :--- | :--- | :--- | :--- | | | Rendering Resolution | 1x PSP or 2x PSP | Start with 1x for stability on weaker devices. 2x sharpens the image significantly for most modern screens. | | | Rendering Backend | OpenGL or Vulkan | OpenGL is the safest and most stable for this game. Use Vulkan if you have a newer device and experience performance issues. | | | Hardware Transform | Off | Some users report improved stability for this title with this feature disabled. | | | Software Skinning | Off | Turning this off can help with performance. | | | Vertex Cache | On | Enabling this can improve performance, especially in open-world games. | | System | Change CPU Clock | 60 (or 333 MHz) | This underclocks the emulated PSP's processor. A value of 60 often resolves severe stuttering and frame drops by stabilizing timing. On real PSP hardware, you would set this to 333 MHz for maximum performance. |
