Assassin’s Creed 3 PC Requirements

Minimum only, though it’s probably not something to worry over.

Well, at least for fellow Smashers:

Supported OS: Windows Vista (SP2) / Windows 7 (SP1) / Windows 8
Processor: 2.66 GHz Intel Core2 Duo E6700 or 3.00 GHz AMD Athlon 64 X2 6000+ or better recommended
RAM: 2 GB (4 GB recommended)
Video Card: 512 MB DirectX 9.0c-compliant with Shader Model 4.0 or higher (see supported list)*
Sound Card: DirectX 9.0c-compliant (5.1 surround sound recommended)
DVD-ROM: Dual-layer drive
Hard Drive Space: 17 GB
Peripherals Supported: Windows-compatible keyboard, mouse, optional controller (Xbox 360 Controller for Windows recommended)
Multiplayer: 256 kbps or faster broadband connection

Supported Video Cards at Time of Release:
AMD Radeon HD 3870 / 4000 / 5000 / 6000 / 7000 series or better
NVIDIA GeForce 8600 GT / 9 / 100 / 200 / 300 / 400 / 500 / 600 series or better

Laptop versions of these cards may work, but are not supported. These chipsets are the only ones that will run this game.

At 17GB, I’m starting to feel inclined to get the retail version instead of Steam; that’s going to be one looooooong download.
