I don't know aince I haven't played either one, it's just that technically, they were originally made for cutting edge technology that is now old, unless they have radically changed them.
On another note, Far Cry outside ran better than the inside levels for me, I blame it on the lighting, that might be an indication of Doom 3 as it is supposed to have really good lighting effects.
carmack says that he starts out coding engines predicting where the hardware technology will be a few years out.. he actually has enough power and sway to move hardware where he wants it to go to match what he wants development-wise apparently...
plus right before NV30 got released he was continually updating how the game interacted with that hardware, and im sure there are now Geforce6 optimizations, especially with that shadowing feature that the GF6 supports now.
John Carmack seems to be really picky about his engines, they are his babies... especially Doom3. He's really been taking his time with the team going over and optimizing everything. im sure the game has been in a playable state for the longest time...they want everything smoothed out and clean.
and I always see people talking about what kind of environments Half Life 2 vs Doom 3 are 'optimized' for, or 'run best with'.
We just havent seen Doom3 ripping through the terrain of mars...the main reason isnt cause the engine cant do it well or do it efficiently, its just not in the nature of the game! you cant walk around on mars...its not scary, and its a little more of a stretch than a space base on mars

But theres no question that the mod community will apply the engine to something more real-life or outdoors, then theres a more apples to apples comparison i suppose.
