I'm still not convinced that Mantle will be a significant motivator for AAA game producers to port to Linux. After all, if an "easier" way to get your game out the door was all that it took, wouldn't we have seen a bunch of Unreal Engine games on Linux back in 2004?
Can you convince me that Mantle is a substantially better or easier way of doing graphics programming than modern OpenGL?
Not sure. I'm surprised myself that there aren't more OpenGL games. One possibility is that OpenGL is too bloated/complicated (which Mantle would fix), but I don't know enough about OpenGL to state that with certainty.
