The official PC specifications for Watch Dogs, which launches on May 27, have been revealed in the game's Steam listing.
The requirements conform to ones accidentally released by Ubisoft's Uplay store in October, including the fact the game will only support 64-bit operating systems.
Watch Dogs, then nearly a month from shipping, was delayed from mid-November 2013 to its current launch in order to improve the game.
For Watch Dogs' minimum specs, players will require a DirectX 11 GPU with at least 1GB of VRAM, along with a quad core CPU and at least 4GB of RAM. Example GPUs include NVidia GTX 460 or AMD Radeon HD 5770, and an Intel Core2 Quad Q8400 or AMD Phenom II X4 940.
Users aiming to reach the game's recommended specifications will require a DirectX 11 card with at least 2GB of VRAM, an eight core CPU and 8GB of RAM. Steam's example GPUs include NVidia GTX560 ti or AMD Radeon HD 7850 and for CPUs the Intel Core i7-3770 or AMD FX-8350 Eight-Core CPU.
Uplay's October leak also listed "Ultra" specifications of a DirectX 11 GPU with at least 2GB of VRAM, an eight core CPU or more and 8GB of RAM or more.
