I have the latest driver for my card, though it isn't a 'new' card. I am also running Vista (yeah, laugh at me)...
Unfortunately your computer doesn't met minimal system requirements for this game. Code: Memory: 2046MB RAM Card name: NVIDIA GeForce 7600 GS You only have 2GB of RAM while PA need at least 4GB (8GB recommended and game really need it). And your video card just way too old too.
What are the hardware requirements? When I read the FAQ, prior to buying the game, it said (and still says): System Requirements – SUBJECT TO CHANGE Currently this is just the “minimum we expect to be needed”. We have not locked down any more specifics about what will be the ideal system to play on, but you will need to support at least the following: Dual core processor Shader 3.0 A decent OpenGL driver – if your card doesn’t come with one you might want to look at some of the 3rd party OpenGL drivers out there. At Alpha Start, the following are also required: 64-bit operation system An internet connection
They're listed on Steam store page: http://store.steampowered.com/app/233250 Those on site is really outdated and was published before alpha was available.
