GTA5 promises to "take full advantage of the power of PC," with various improvements such as higher resolution and graphical detail, denser traffic, greater draw distances, upgraded AI, and advanced weather and damage effects.
The epic open-world game will also feature "new wildlife" and a video editor for advanced movie-making.
GTA5 for PC includes Grand Theft Auto Online, and the listing promises that all content added since launch - including such things as new jobs and customisations - will be present in the PC version. As previously promised, multiplayer progress will carry overbetween the PS4, Xbox One, and PC versions.
Steam lists its release date as Fall 2014.
