A lot of mods are going to fail at the start of Half-Life 2; this can be seen throughout history in other games. It might even be possible that every mod listed in the poll will fail. So this is sort of pointless.
Yes, clock speeds for processors are measured in Mhz and Ghz respectively.
AMD uses a numbering system to denote performance (Not completely accurate), but their clock speeds are still measured in Mhz/Ghz.
I think people are mistaken on their views.
Everything might have been finished in September 2002, as in, the art or the basic core components to the engine. However, it doesn't mean that when Half-Life 2 ships, it'll be this amazing piece of work totally different and improved from what was...
The reason why Intel's MRM tech would have been a godsend to modders is not because it looks better (though it doesn't look too bad), but because it would save modellers a lot of work. Not only that, but it would save memory and disk space for more important things you want to include in your...
Here's a better answer I received from Valve on the matter:
"The CPU overhead for MRM cost too much. It was originally designed for an environment where per triangle costs versus tesselation were much higher than they turn out to be if you organize them in a hardware-friendly format...
