I wonder what the percentage is when you figure the entire "computer" gaming market (eg. consoles, tablets, and phones). I suspect Microsoft's dominance on gaming is (and will become even more) weaker than we believe.
OpenGL seems like a no-brainer for future survival as MSFT platform dominance exhibits entropy.
Is PS3/PS4 development OGL or a proprietary API? Because if it is OGL then yes that makes said API far more useful for sheer amount of access to hardware.
It looks like in 10 years, Linux and OSX adoption will _probably_ approach 50% market share. Therefore, the best choice for my new game, which will be released in 3-4 years, is to choose OpenGL
I'm not a game developer, but I would bet they are interested in where the market will be in the medium term, and there is no indication Linux/OS X will suddenly dominate within that timeframe.
On traditional PCs and Macs, Microsoft
still owns an overwhelming market share,
with 91.8 percent of all traffic coming
from Windows-based machines. Among non-
Microsoft operating systems, both OS X
and Linux have stalled since October
2011, hovering around 6.9 percent and
1.2 percent, respectively.
Market share if one thing, but we are looking at a segment of gamers which may be split differently. Who says there isn't a larger proportion of Linux gamers in that segment, for example? If Humble Bundle is any indication, it looks like the Mac gamers segment and the Linux gamer segment is actually pretty close in size.
