The simple fact is that code quality tends to improve as you move between platforms... non-obvious bugs on Windows become VERY obvious in the Linux p… - Ryan C. Gordon

Q3A is probably one of my favorite codebases to have had the honor to work with. There’s just so many places where you get these “holy shit, that’s a brilliant idea” moments. I don’t know what Doom 3 looks like under the hood, but Quake 3 was a real marvel of engineering as much as anything else.

I happen to like the "feel" of OpenGL more, which isn't something I can explain well to those that aren't programmers, but I don't think it matters much at this point which API one chooses. More or less, you have feature parity between both APIs, both have made a handful of design mistakes, and both do a few things in slightly more pleasant ways than the other. Of course, the unforgivable thing about Direct3D is that it only works on Windows. If it was truly cross-platform, though, I wouldn't really object to using it. But since you write OpenGL almost everywhere, and Direct3D almost nowhere, it seems like a false choice to me.

If I'm the only one pushing Linux gaming, we have a serious problem. I'm happy for the contributions I've made, but I would be happier to know that Linux gaming can continue if I get hit by a bus. There are others out there doing what I do. You should interview them too.
