One of these limitations was a 512MB memory allocation limit that required the game to limit its texture streaming, draw distance and loadable objects. When GTA San Andreas released in 2004 it had a multitude of limitations placed by the computer hardware at the time. This mod is available in the form of an ASI plugin as well and is available over at this link.
This mod functions similarly to how GTA 5's first-person mode works in which the player simply cycles camera positions with the camera button (default V in this mod) until they're in first person. Players can can cycle between cameras until they are in first-person mode. Experience the world of San Andreas like never before with this mod.
