    Fully expect it to be exclusive and driver dependant/controlled, much like physx is on Nvidia cards, theres no reason it couldn't run on AMD cards, but both want a competitive advantage. Why should AMD enable this on Nvidia cards whilst Nvidia don't enable their tech they put their R&D time into on AMD cards.

    There is a cost to developing these technologies and they recoup by shifting boxes.

    TRESemmé professional, affordable
    On a more serious note, i would have expected a video showing it off not just stills.

    nVidia has those fancy hair-stuff for some time now, but noone has really implemented it into their games, so why should anyone consider the solution made by AMD? Maybe because the new consoles have an impact on this with their AMD-hardware.

    In general: old news is old.

    Pity there isn't a video.

    This is actually something I think could potentially be really good (if it's well implemented and widely used) since hair is something that normally really does remind you you're playing a game.

    But Nvidia's implementation of PhysX is written in CUDA, which (given they hired the guy who invented it) only works on Nvidia hardware; TressFX Hair, by contrast, is written in DirectCompute, which works on both Nvidia and AMD hardware. Thus there is a technical reason (born, admittedly, of a marketing decision) for PhysX to run exclusively on Nvidia hardware that does not exist for TressFX Hair.
    Well then AMD is ahead of the game, 'cos they've already got one win in the bag: as the article states, Tomb Raider features TressFX Hair technology.
    Given AMD only announced this late last night, after teasing a couple of hints a day or so ago, I'm curious as to how you're categorising this as "old news." I should be building a time machine and bringing you news from next week, perhaps?

    Just received confirmation from AMD: TressFX Hair is compatible with any DirectX11 GPU, including those made by Nvidia. I thought as much - what a cleverly-worded press release!

    That is great news to be honest, it would be beneficial to consumers if both NVidia and AMD shared software tech more.

    Just updated the update - as well as word from an unnamed spokesperson (Pro Tip: if a journalist quotes a "company spokesperson," what they actually mean is "PR person from a third-party outfit hired to represent the company" - but don't tell anyone I told you that, it's a secret) I've received the following from Devon Nekechuck, AMD's terribly genial product manager for the High-End Discrete Desktop Graphics division:

    It's old because nVidia is showcasing this technology for over a year now.

    AMD must have paid alot of money to get this implemented into Tomb Raider, or it's because of the new consoles using AMD-hardware.

    No, Nvidia hasn't been showcasing anything like this. You show me a single DirectCompute-powered hair rendering engine released by Nvidia. Go ahead. I'll wait here.

    Now, what Nvidia *did* release a couple of years back - and the release that, I believe, has you confused - was a demo of a hair-rendering engine. This engine was not available to developers as a plug-in they could add to their games, and nor was it new even then: Nvidia has been working on realistic hair rendering for years. Heck, here's a SIGGRAPH paper from 2008 all about the subject.

    Compare and contrast with AMD, which has released a working hair rendering engine that is compatible with all DirectCompute-enabled graphics cards and can be licensed right damn now for inclusion into a game - hence its appearance in Tomb Raider.

    That is what we in the business call 'news.'

    glad to see it's not going to be an exclusive. Nvidia's PhysX was a great graphics feature that almost no one has used since mirrors edge because it was proprietary, developers don't want to invest time in a feature only half of their fans will be able to use.
