On DOOM 3 Framerates

[Oct 22, 2003, 6:18 pm ET] - Share - Viewing Comments

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.

Re: Why 60, when flicker-free is ~72Hz?

Actually, you can tell between 60hz and 75hz refresh rate on a monitor because the display is actually going dark and being re-lit again when the gun comes back around. Frames per second in a game != Hz refresh rate. Take a LCD screen for example, if its 15hz or 60hz, the image is rock solid and you can not tell the difference until fast motion occurs. If Doom 3 runs at 60 frames per second, the difference between 60 frames per second and 75 frames per second on a 100hz refresh rate monitor, I bet you would have a REALLY hard time seeing the difference.
