A position they abandoned for Horizons... making something unavailable a requirement.
Jeez...you really are twisting everything to fit your mindset, aren't you? Do you
honestly believe that FD arbitrarily chose to implement compute shaders to the detriment of any platform?
They were
forced to abandon it because to restrict Horizons to the feature set that OS X supported - in order to make the game experience the same on all platforms - would've meant a drop in quality across
all platforms. It wasn't a case of, "You know what? I can't be porting this version to the Mac, so let's just drop it and save ourselves hassle".
The point is that it
could have been done in DirectX 10 - that was a possibility, although there would've been a lot of work involved. Implementing it on OS X was an
impossibility. Do you understand the difference?
You posited that they were happy to abandon OS X users - that isn't true at all, which is what I was trying to say. The reason they abandoned it is that no amount of money or effort would've made it possible to do so because the operating system is fundamentally incapable of supporting the game.
Of course, all of this could easily be solved by FD doing another Kickstarter campaign to port it - estimate the work involved, and see if it'll be funded. That's the easiest way to put the whole argument to bed.
