Sony has released Gran Turismo 5 patch 1.02 - which should fix many of the title's online multiplayer problems.
The update allows the game to take advantage of Sony's upgraded servers - which are super-powerful to deal with immense numbers of racers.
The update will also enable maximum power and weight restrictions for online races.
Polyphony boss Kaz Yamauchi has said that the patch will double the game's online capacity from 500,000 to one million simultaneous connections.
Gran Turismo 5 went on sale around the world on Wednesday morning.
