PGXP

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.

Features

• 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 eliminate the wobbling polygon issues. Second, it adds perspective correct texturing to stop the ‘texture warping/dancing’ issues.
