Measured gpu usage with afterburner, questions

[Koroshima]

I have the same card (EVGA GTX 470) using 280.26 and read mid-to-very-high (often a constant 99% in "heavy detail" situations) GPU usage in-game. At what settings and resolution do you run the game?

Also, while those are nice card temperatures, in the future you should also post idle temps, since temperature readings by themselves are highly subjective and harder to use without a gradient to compare against.
