i can remember being on PS3 and having a 1.65Mbps connection and it would take 2 days just to download patches back then. They weren't that big. 16gb used to take 3 days to download. 63gb would take forever at that speed
its essentially a new game... how big was original install size?
PS5 initial install size was 104gb.
this patch starts as 95gb but shrinks as you download it to 59gb. Its still a fair chunk of previous install size. No idea what install size is after patch though.
