I've noticed that in 3D psx games on epsxe the polygons tend to shift around a lot. They seem to fluctuate or morph to and fro as the characters are moving. I just want to know if this is a natural effect, and if there's any way to lessen it or make it less noticable. I would also like to know if there's a way to filter 2D graphics without getting the tile effect. I remember VGS used DirectDraw acceleration to filter the graphics smoothly.
