On DOOM 3 Framerates

DOOM 3 Capped on IGN (thanks Frans) relates a tidbit about DOOM 3 gleaned at a recent NVIDIA editor's day, where they learned that the game will be capped at a maximum 60 FPS framerate. They quote id's John Carmack on the reason for this.

"The game tic simulation, including player movement, runs at 60hz, so if it rendered any faster, it would just be rendering identical frames. A fixed tic rate removes issues like Quake 3 had, where some jumps could only be made at certain framerates. In Doom, the same player inputs will produce the same motions, no matter what the framerate is."

In a mostly unrelated note, we'd like to thank IGN for doing a story today on DOOM 3 and NVIDIA (who prefer their name be shown that way in print) to help celebrate INTRNATIONAL CAPS LOCK DAY.

I think the person who did the article got fps mixed up with Hz. He/she says 60fps max, while John says 60Hz. That's not the same thing.

Yeah, but from the John Carmack quote above, you can see that the game updates the position of everything at most 60 times per second. So yes, you can have your video card draw at 1 billion frames per second, but if it's drawing the exact same thing, it's the same as leaving a still picture on the screen.

How it'll relate to benchmarking, I don't know, but to the player it'll effectively be a maximum frame rate of 60 fps.
