No shit, MS should be ashamed of that bloatware thing that is directX, it's always been slower than other 3D grapics API out there (Open GL, Glide) however it was better supported.
I am not saying that better support and promotion of its use are bad reasons for the adoption of the API, these are very important factors, despite the technical merits and shortcomings, however, it would have been preferable for PC gaming if open GL could have been pushed further (it seems to be happening now, so hopefully that will change...).
Mantle seems great, can't wait to see games that run on it! it's like a free upgrade!!!
