Comment This might very well become AMD's tombstone (Score 1) 71
AMD, with their decreasing market share, should use open, or at least widespread, standards such as OpenGL or DirectX.
Remember AMD's alternative to NVidia's CUDA? I think it was called Fire- something or something-stream... that really went well.
If AMD opens up a new front here, and Mantle has any success at all, NVidia will retaliate by creating their own API, and guess how many people will use Mantle then.
