@ Andrew: Thank you. You are a good man. By "GK" I meant the entire Kepler line-up. I don't really think that 32 bit float reverse z-buffering is always sufficient (like it isn't with PCSX2) but then infinite precision isn't possible and many programmable methods (as well as other hardware instructions) can be used to work around less machine precision. There will always be precision mismatches and it is generally better to focus on the present and future than the past. However, the DX specs have been terrible for backward compatibility while OpenGL is about to be a better balance (OpenGL was usually better for programmers who had a high tolerance of ambiguity and it would've generally been best or very competitive if it weren't for Microsoft's patents).
[rambling] Anyway, I wish that there was more free competition in graphics hardware and that nvidia didn't prey on ignorance as much as I think they do to make profits. Nothing radically different has launched since G80 launched 8 years. Driver features are taken away more than added (and I am pretty sure that they have been using subtle lossy depth optimizations for all the drivers that I tried with my 780 and the 660Ti I sold). I mean, PC gamers often avoid consoles because they like choices. I understand that I couldn't always tell the difference, but we could specifically charge more/differently for special drivers, and/or for support, not use NDA contracts, be more tolerant of anonimity (especially if it is accidental), not put such a retainer on people in the Focus group, etc., etc. But then maybe there would be too many choices for people to make. In any event, the intellectual monopoly system is way too powerful (and that is not the only way large corps are perpetuated aided by the ruling class in the central aggression agency aka the u.s. government). Wealthy companies and individuals shouldn't have the privilege to legally sue poor ones. I also believe that that Nvidia has been helped more by the presence of the patent system than hurt by it, as it ultimately sent a signal to 3dfx that helped end 3dfx (as did their contract suit against Sega).
Jen Hsuang is a good man, but I think he is a very powerful and possibly not-so-democratic CEO. Perhaps someone like Michael Katz would be better (although Tom Kalinske was good, Sega's prices got high as hell even under him and while Bernie Stolar was good he set the U.S. launch price of the Dreamcast too low and including a 56k modem was the worst thing that could've been done for the future or for Sega's profits (perhaps he was trying to make Hiro Nakayama angry)... early adopters and especially my parents would've paid a lot more for the DC even though even I knew that the Dreamcast wasn't going to last long). I know i would be worse and even less democratic than Jen Hsuang (his deductive reasoning is top notch while my inductive logic obscures the truth and my deductive logic doesn't as quickly yield truths like JH's does) and I ain't the only one.

Finally (for now), I offer apologies for coming back as well as for the incoherence and/or other ambiguity in any of my posts, past, present, or future. I am thankful for this soapbox even if I am not welcome to it. I offer further apologies if I am not welcome.
