Demonstration of how PGXP gets rid of zigzagged lines in Tenchu
Note: Loading screens are cut out of this video in order to get to the point.
The PSX has no Z-buffer and therefore can't really do 3D properly. Because of this, textures will sometimes appear misaligned. A very good example of this is in the training level of Tenchu, where the floor is textured with wooden planks. When viewed horizontally, they look straight but from a lateral view they are wibbly-wobbly.
PGXP operations in certain emulators such as PCSXR and mednafen-beetle-Hardware-libretro core (used in the video capture here) are able to correct the textures so that they face the correct direction at all times. This leads to much better graphics in many games and also helps to reduce the wobbling and jittering seen in many 3D models while cameras are panning.
