AMD's Gary Silcott told the INQ "they [Nvidia] would intentionally damage performance to make Nvidia GPUs run the same app better." Then, perhaps thinking better of accusing Nvidia of hypothetical, yet outright, sabotage, Silcott added "Even if it wasn't intentional, it would not be optimized for our instruction set architecture like our own SDK."

That's okay though, since Nvidia has no intention of adapting its GPUs for AMDs technology either. "No, I don't see us supporting Steam..." said Nvidia's Derek Perez acidly when we asked him for his response.
