We've just recieved an email from Valve's Doug Lombardi about the System Requirements for Left 4 Dead. A recent update emerged quoting incorrect system requirements on the yougamers.com website, Doug confirmed that they are incorrect. And attached the real system requirements from the actual box:
* OS: Windows Vista, XP or 2000
* CPU: 3.0 GHz P4, Dual Core 2.0 or AMD64X2 (or higher)
* RAM: 1 GB for XP / 2GB for Vista
* DISC DRIVE: DVD-ROM Drive
* HARD DRIVE: At least 7.5 GB of free space
* VIDEO: Direct X 9 compatible video card (Video card must be 256 MB or more and should be a DirectX 9-compatible with support for pixel shader 2.0)
* SOUND: Direct X9.0c compatible sound card
only thing to expect is gameplay and storyline.
