GTA 5 big updates every launch, is this normal?

I installed GTA 5 on my PC on Friday, but every time I've launched it since, there have been huge updates to download:

Download history:
Friday-60GB for the initial game install
Saturday-14GB update
Saturday-close the game for an hour, re-launch, another 12GB update
Sunday- 8.5GB update, close game, re-launch, another 5.5GB update
(at least it looks like they're getting smaller :S )

Can anyone confirm if this is normal behavior to have to download so many large update files in such a short space of time?

Solution 1:

The problem with GTA 5 is that it won't download each update after each other.

For each patch you need to restart the whole client again. I've figured this much out since installing it last week on my new computer. I wanted to go straight online but every time I launched it, it would kick me out of online and said that the version wasn't up to date. After 4 or 5 updates it would finally allow me to play online.

In the initial launch of GTA 5 on pc the retail version didn't have the day one patch, which contained around 5 gigs of data. They won't update the retail package so of course those 5 gigs needs to be downloaded every time when you re-install the game from disc(s)

I can't provide proof other than my own experience but this is what I figured out through it

But where you downloaded 60 gigs at the start is really weird, it's more like you didn't install the game and had to download it seperately
