I doubt that GTA Online released the game with 60K+ items in their online store.

The runtime for the release day store inventory count may have been okay, but I don't think that Rockstar kept profiling their game every time that they modified their store inventory.

The amount of pain Rockstar inflicted on their 90K+ users shows that Rockstar didn't care that their game took more than 3 mins to startup for the majority of their users.

As someone who worked on a smaller, but still millions-of-users live-service game, profiling of average resource usage and the loading screens was done periodically even if there were no code changes to the area of the game in question.

Given that our team was over an order of magnitude smaller than Rockstar, I would be very surprised if they did not have anyone even casually browsing a profiler every 3 months or something, though I think at their scale (LinkedIn claims 5k employees) they can probably have a team or two where everyone's entire job description be performance maintenance.
