| Setting Category | Recommended Value | | :--- | :--- | | | Set to Vulkan for maximum performance on modern devices, or OpenGL if you experience graphical glitches. Vulkan is generally recommended for its stability and performance. | | Rendering Resolution | This is the key to "Extra Quality." The original PSP ran at 480x272. Set this to 2x, 3x, or 4x PSP . This upscales the game to near HD (1080p) quality. If your device lags, lower this to 1x. | | Display Resolution | Match this to your native screen resolution to ensure full-screen play with minimal scaling artifacts. | | Texture Filtering | Set to Linear or 16x Anisotropic . This smooths out the textures on walls and floors, removing the "blocky" look of old games. | | Texture Scaling | Enable "Upscale" and set to 2x or 3x. This attempts to re-draw the game's textures in higher detail. This will use more battery but looks incredible when you have a good phone or PC. | | Screen Scaling Filter | Try "LCD 3x" or "Sharp Bilinear" . This gives the screen a more vibrant, crisp look. | | Post-Processing Shader | Select "Natural Colors" . This corrects the washed-out look of the original game and adds contrast without bogging down performance. | | Frameskipping | Set to "Off" . Frameskipping boosts performance by dropping visual frames, but it ruins smoothness. You want a "lag-free" experience, not a "jumpy" one. | | Anti-Aliasing (MSAA) | If using Vulkan and you have a strong GPU, turn on MSAA (2x or 4x) to get rid of jagged edges on character models and environments. |
