GTA San Andreas vs GTA V part 2
The second part, and this covers the graphics, light, physics and animation.
The move of the GTA series from rigid poligons to a very flexible, to almost non existent collision and physics to a realistic effects is awesome... but the greatest achievement is the light effect, in the past GTA games, there was literally no shadows, little light reflection and so on, now the lights effect in GTA V makes the job well done even in 7 years old consoles.
The textures in GTA SA are not great... in Driv3r was better in any graphic feature than GTA SA, but way behind in gameplay and story. Still, the textures in GTA V looks like a modest improvement from The Ballad of Gay Tony. The physics almost the same and the animations looks a bit better than GTA 4.
