I was just wondering, if anyone knows, why are Half-Life 2 and Doom 3, from what I understand two of the three best looking games out there, powered by two different components mainly.(This probably doesn't make sense, read on) For example, I saw a post that said if you have a Athlon 64 3700+ and a NVIDIA 6800 Ultra running DOom 3 on top settings, You would get 65-80 FPS. Then it said that you could downgrade to say a 2500+ and only lose 10-15 FPS, where as you could redo the exact same scenario with Half Life 2, and downgrading the proccesor would render it almost unplayable. And same case with Half Life 2. I heard you could go from a 6800 Ultra to a NVIDIA 5700FX and still run it on near top settings so long as you have a top of the line proccesor powering it, where as you could do the exact same thing with DOom 3, and it would be rendered almost unplayable. If anyone knows that would be great, I'm just curious.

From what I've gathered, Doom3 has gone all-out on special effects - shading, lighting, the works. All these effects are handled by the graphics card, thus the reason the card is very important for DOOM3 - The game engine hasn't consentrated so much on "real-world" physics - making things behave as life-like as possible. Half Life 2, on the other hand, while looking great, doesn't use all the latest and greatest special effetcs, thus a slightly lesser graphics card can handle it fine. However, Half-life 2 has concentrated on real-world physics - making things move right when they're hit by an explosion or bullet. These calculations are carried out by the CPU, and so the reason that is important for HL2.
