I mean GTA Online is a microtranscation/grindfest experience, mostly to milk kids of their money. It's not really worth the time due to how grindy it is.
Most PC gamers play multiplayer mods like RageMP that allow connecting to servers with well-made scripted gamemodes like RP, but also stuff like death match where hackers are actually banned I'd guess.
Played recently and thought Rockstar must not have actioned the advice in the blog
But no it's just it is still slow but they did fix these issues kudos to them but performance still needs attention
People who play this regularly have their phones out/youtube videos on waiting for these load times
