#PlayStation #PGXP #Warping #correction #perspective The original Ridge Racer Game with 'corrected graphics' is shown here using the RetroArch Beetle PSX HW core.
Back then we were mesmerized by the awesome 3D graphics of the little grey box, but the GPU had quite some limitations when it came to precise calculations needed to correctly map textures on polygons. Jittery graphics, warped textures, jumping textures were all part of what the original PlayStation charm.
- Wobbly polygons (lack of subpixel precision)
- Dancing/warping textures (lack of perspective correct texturing)
Emulators preserving the functionality of the original PlayStation have upped the game and have for years been improving the graphics by filtering the textures and upping the resolution, but the jumpy texture warping and zig zagging lines remained. Or have they?
The GPU flaw was (partially) corrected within the RetroArch Beetle PSX HW Core using PGXP (PGXP introduces subpixel precision to get rid of the wobbling polygon issues and it adds perspective correct texturing to stop the ‘texture warping/dancing’ issues).
Kudos to Cat Butler - he’s the one who created PGXP, here is his YouTube channel:
