As we know, Half-Life 2 was arguably the biggest gaming story of 2004, which achieved a status of 'instant classic' and is quite often labelled 'The Best Game Ever to be made'. Last night on Attack of the Show, an American TV show focused on gaming, Valve software unveiled a whole new level for Half-Life 2 that will give gamers a glimpse in to the future of PC graphics, with some immensely realistic lighting effects, known as HDR. Valve's Doug Lombardi gave a demonstration of the upcoming 'The Lost Coast' level that utilizes technology that was implemented in to the Source engine which, until now, has not been seen in a game based on the engine. The technique has, however, been seen in the likes of FarCry and Splinter Cell: Chaos Theory - the full version of the latter is released today. HDR is an abbreviation for High-Dynamic Range Rendering, and creates an amazing leap in lighting realism. We saw how Crytek's method of HDR was implemented back in our FarCry patch 1.3 evaluation, which is only possible on video cards supporting an FP16 frame buffer and Shader Model 3.0 capabilities. Splinter Cell: Chaos Theory also requires a Shader Model 3.0-capable video card to make use of the lighting technique. Valve's HDR method is slightly different in that respect. Half-Life 2 is a title on ATI's 'Get In The Game' program, so it would be a marketing disaster if the new lighting technique did not work on ATI's current video cards. "This is targeted at the super-hardcore early-adopter guy who's got the latest and greatest stuff and the horse power to cope with these new lighting techniques," said Doug when asked how demanding this new lighting technology would be on today's video cards. The Lost Coast will be an additional level that is free to owners of Half-Life 2 and it will be released via Steam in the next few weeks. There will also be an update to Half-Life 2 that will give the game some of these HDR effects released in the same time frame.
