Waiting for loading in Grand Theft Auto is a very annoying thing, not only in the single-player version, but also online. This is because of its wide level. However, this player has found a more efficient way so you don't have to wait for it to load any longer.
A player named T0st found a way to speed up loading GTA Online by up to 70%. It found that there was a single-thread CPU bottlenect when running GTA Online and the game was struggling to parse or parse a 10MB JSON file. This is because the parser of the JSON file is not properly developed by the developer.
He then explained that with his parser, he managed to reduce the loading time of GTA Online from 6 minutes to about 2 minutes. You can read the method further via the following link.
But for those of you who don't want to read, you can visit the booster he made himself via the following link. Before you download it, T0st reminds you not to change anything in the game when it is in online mode because there could be a failure and it will actually damage the game files or worst get your account banned.
