World of Warcraft (We tested it at AMD when I was doing work for them...as an OpenGL sustaining engineer...)
Oh, you meant recent stuff...hm...
Chronicles of Riddick: Escape From Butcher Bay (Yes...)
Portal (MacOS version...)
Heh...name one...just go looking around- there's quite a bit.
Nope. It wasn't a "better" one. It just exposed "nifty" stuff that might have "simplified" some of the graphics effects programming.(b) Obviously, considering that Direct3D is the better programming API. Long Peaks might have changed that, but Khronos backed off before it was complete.
They're not awful- they're poorly implemented in the case of some aspects thereof (differing ones for NVidia and AMD...)- and this isn't the fault of the API and more a fault of the vendors not putting quite enough manpower against the issue in question. And, more to the point, this doesn't fix that issue- a D3D state tracker won't magically make it "better", full on drivers with it might, but then they'd also make the 3D stack situation with OpenGL better as well.(c) MS taking de facto ownership of 3D wouldn't be such a bad thing, considering how awful the 3d stacks on Linux/BSD/Mac/Unix are.
