Valve unveiled a 64-bit version of its Source game engine technology today. The first 64-bit Valve games released will be native 64-bit versions of Half-Life 2 and Lost Coast, and have been developed to take advantage of AMD Athlon 64 FX processor-based systems - the ultimate 64-bit gaming platform for PC enthusiasts.
The 64-bit versions of these games are being offered to all Half-Life 2 owners via Steam, Valve’s online platform for delivering games and digital content directly to users around the world.
Half-Life 2 has been named Game of the Year by over 35 publications worldwide, and has sold over 4 million copies worldwide. Source, Valve’s proprietary engine technology, provides technical advances in rendering, artificial intelligence, character animation, and networking.
