Grand Theft Auto 5's PC port has received its first patch, solving numerous errors.

Chief among these include an issue wherein certain Windows usernames would prevent the launcher from working.

Another issue this patch fixes is player character's faces erroneously getting transferred from the console to PC game.

It also fixes a glitch causing the launcher to use more CPU bandwidth than it should, resulting in the game crashing.

Added a grid to the Golf mini-game to show the topology of the green while putting.
