Valve's announced the release of 64-bit versions of Half-Life 2 and super-shiny HDR add-on Lost Coast through Steam.
The 64-bit versions, which should be available now, have been developed specifically for AMD's line of Athlon 64 FX processors.
"Bringing the Source technology to the AMD64 processor platform is an important step in the evolution of our game content and tools," according to Valve's Gabe Newell. "This investment in future processing will allow us, and third party developers working with Source, to push the boundaries of the gaming experience."
It's all a bit airy-fairy in terms of particular benefits, but we expect that anybody packing a 64-bit processor knows what to expect, even though Half-Life 2's one of the first games to take this particular plunge. Let us know what you make of the change.
