that isn't true. you can get a LOT more than 60 fps, but anything greater
than 60 fps is simply replaying the same textures more than once.  This is
from that tweak site quoting John Carmack:

John Carmack of id sofware: "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."
