I know there's been some discussion about the machine specs needed for the alpha test, as we're approaching the first build delivery I can share some of the development specs of where we are at the moment. Optimisation and performance are obviously ongoing tasks and as more features are added through the alpha and beta periods we'll need to keep revisiting it.
To play the first build released in December we're currently looking at the following:
Direct X 11
Quad Core CPU ( 4 x 2Ghz is a reasonable minimum)
2 GB System Ram (more is always better)
DX 10 hardware GPU, 1GB video RAM(my reasonably low end machine has a GTX 285 with 2GB)
As I say we're looking to try and reduce the spec if possible through detail options and optimisations, so the final min spec for the game should be lower than that stated above, but for the initial alpha tests you'll need to be in that range.
Edit: Minimum video ram spec updated to 1GB.
