Reports spread of t0st's discovery and Rockstar has confirmed not only that this works, but that it will release an official fix in a future update for the game. They created a fix they claim enables the game to load 70% faster, and included a message for Rockstar, advising that the issue 'shouldn't take more than a day for a single dev to solve.'
The modder, who goes by the handle 't0st,' recently posted their discovery of a single-thread CPU bottleneck that occurs in the PC version of the hit multiplayer mode. Rockstar Games has paid a modder $10,000 for identifying a way to make Grand Theft Auto Online load significantly faster.
