I'm currently installing Gta 5 on my laptop but it only takes up 43Gb. That's not normal, is it? It should actually be more
Wait, there's probably something else to come
That will probably be the installation file for 43 Gig. The data is packed and then that's bigger.
In addition, it can be an older version that is installed (I'm not sure how Rockstar works there) that is then updated.
