Sony's PlayStation 4 Is Running Modified FreeBSD 9
Well, one thing is clear, you don't like OpenGL. On the other side there are thousands of programmers who just use it, and weirdly enough it seems to work for them. Btw not sure if you knew this, but it is possible to wrap OpenGL with a minimal interface which deals with most of your complaints. I saw this happen and I heard the VALVE guys have got a decent wrapper too.
Yeah, all posts here about OpenGL including those detailed posts from elanthis are naught but FUD. If you are used to D3D you might not like OpenGL simply because it is different. I myself prefer a more UNIX strict system such as Solaris or BSD over Linux but that's simply because I'm more used to these systems and because they are more conservative when it comes to applying changes on how things are configured.
The fact is that Valve ported Left4Dead to Linux using OpenGL and the result was that the frame rate was about 10-20% higher than when booting onto Windows and using D3D on the very same machine. That was a fact in spite of the poorly written GPU drivers for Linux and despite how "unoptimized" OpenGL is. So just imagine how things would be if people really started working on the optimization bits on the Linux system and started optimizing the drivers. I'd say Windows and D3D would be smoked big time and I think Microsoft people know it which is why they put so much effort into spreading their FUD.
You may prefer D3D over OpenGL or the other way around for various reasons, but you cannot state as a fact that D3D is "superior" or whatever than D3D because D3D does have obvious weaknesses compared to OpenGL as stated above. A while ago I read the following post which is a recommended read:
Well you're going to need a modern upper midrange machine or better (preferably 8 cores and a GPU > 2TFLOPS) and you need to figure out just what changes sony made to their distribution of FreeBSD including whatever display server they're using (Probably not X.Org but their own thing) and port those over to Ubuntu and install the FreeBSD variants of various libraries and then you might be able to run them...
And where would you get a PC with Unified RAM? Nowhere.
Just because according to this fake report with doctored screenshots the PS4 OS is allegedly based on a PC operating system does not make the PS4 a normal PC.
Xbox One runs a version of Windows 8. Good luck getting X1 titles to run on normal PCs…

Don't forget that "porting" to OpenGL means using the togl library, which translates DirectX to OpenGL on the fly (the game still thinks it's talking to a DirectX device). This translation layer should in theory slow things down, but the opposite is the case. That alone speaks for the efficiency of OpenGL.
D3D vs OpenGL is an none issue. Since version D3D10 and OpenGl 3.0 /OpenGL ES 2.0 here is no real difference in how you use it. They are both just glorified ways to feed data to the different shaders. There are some "plumbing" issues that one can simply abstract away.
The claim I replied to was that and modern PC would suffice but not a single currently available PC has the required architecture to run PS4 software. Aside from that, the screenshots are still fake.
Therefore: No currently available PC with Unified RAM architecture and no credible evidence that PS4 OS is really based on FreeBSD which means that mike4 and Luke_Wolf won't be able to play PS4 games on stupid Ubuntu anytime soon.
