Alt-T = Frame-limiter. The other keys are:
================================
Alt-R: Frame rate display toggle.
Alt-M: Three-state toggle for mirror: none, medium detail,
high detail. Defaults to medium. Anti-aliasing takes
place in hi-res mode only.
Alt-W: Three-state toggle for weather: day, night, and rain.
This is a 'for fun / showing off' feature and is not a
realistic gameplay feature; e.g., traction does not change
in 'rain' mode.
Alt-K: Sky optimization toggle: This defaults to off. Can speed
up frame rate at the expense of occasional graphical
glitches, especially on the horizon, when viewed at an
angle (like at Michigan when on a banked turn). May
not be a significant speedup unless you are in Turbo
mode and / or running on a track with no textured sky
(clouds). Only really useful for showing off "maximum
speed mode".
[Technically, can causes glitches on any non-textured
polygon that spans entire screen horizontally, like
when going under some bridges or facing sideways]
Alt-A: Anti-aliasing toggle. Anti-aliasing smooths the jagged
edges of the graphics on screen.
Alt-T: Timer toggle ('Turbo mode'): When the timer is 'off', the
physics runs at the frame rate: it will be slower than
reality at less than 30 frames/sec, and faster than reality
at greater than 30 frames/sec. Advantage of 'off' is when
the timer is on, the frame rate cannot exceed 30 fps. Can
cause sound problems, especially in big crashes with lots
of smoke and dirt where the frame rate becomes low. Should
NOT be used in dual / multiplayer mode. This is a 'for
fun / showing off' feature only and comes with no warranties.
Alt-X: "Maximum Speed Mode": Frame rate display on, mirrors off,
sky optimization on, anti-aliasing off, timer off. When
toggled off, reverses all these settings, regardless of
their previous values (i.e., restores default).
Print Screen Dumps a 24-bit PCX screen shot to the race directory,
named ICR01.PCX, ICR02.PCX...; note that it always starts at
ICR01 and overwrites any existing PCX from a previous
session.
Default settings:
Anti-Aliasing on
Medium-resolution Mirrors
Timer on (realistic physics)
Sky optimization off
Day weather mode
Frame rate display off
NOTE: These settings are not saved to disk between sessions.
