Hackaday

The original PlayStation's distinctive wobbly, jittery graphics resulted from hardware limitations rather than design choices. The console lacked a true 3D graphics chip and Z-buffer, forcing CPU-heavy rendering. It used affine texture mapping without perspective correction, causing textures to shift and wobble. Missing mipmapping support led to flickering effects, while nearest-neighbor interpolation created shimmering edges. Integer-only calculations in the Geometry Transformation Engine instead of floating-point math introduced additional artifacts. Combined with slow CD loading compared to N64's cartridges, these constraints shaped the PlayStation's visual identity and influenced game design decisions like fixed camera angles.
