PSP games set a fixed internal resolution (usually 480x272), and the PSP hardware handles rendering at that resolution. Effects like anti-aliasing or blur are baked into the game itself. Emulators like PPSSPP upscale this internal resolution by integer factors (x2, x3...) for performance and accuracy. Non-integer scaling (like 1440p) can cause artifacts or blur, which is why it's avoided
