PGXP (Parallel/Precision Geometry Transform Pipeline) is an enhancement for PlayStation emulation that produces high precision fully 3D geometry data that was not available on the original console hardware.


  • High Precision Vertex Data (more stable geometry)
  • Reduced Triangle Culling (more detailed models)
  • Perspective Correct Texture Mapping (reduced texture distortion)

First, it introduces subpixel precision to get rid of the wobbling polygon issues. Second, it adds perspective correct texturing to stop the ‘textue warping/dancing’ issues.
