I've been playing MediEvil lately and it got me wondering, what causes some of the old 3D games have "flowing" graphics when moving? It's present in games like Final Fantasy VII, MediEvil, i remember Dungeon Keeper 2 having the same thing in zoom mode, however f.e. Quake 2 didn't have this "issue" and it's just as old. The resolution doesn't seem to be the problem, everything is rendered perfectly fine when you stand still. So is the game refreshing slowly or it's something to do with buffering?

The way I understand 3D rendering, polygons are transformed using several matrices, and they are then clipped if they are not inside a certain box, before projecting the box onto the screen.
