# REXP01 - Excite Truck
[OnFrame]
# This game's logic runs at a fixed rate of 60 FPS. During normal
# gameplay, the game checks how many physics steps take depending
# on time passed, then going from a loop this many times.
# (Note: during a car crash, the game runs in slow motion and
# renders interpolated frames at an uncapped speed, which is worse.)
# The complexity of this prevents Dolphin from idling,
# meaning that if the emulated CPU is overclocked more than
# necessary needed to run the game at a stable 60 FPS), the
# emulation performance is going to be worse.
#
# The first line adds a call to `VIWaitForRetrace` (after
# `GXSetDrawDone`) so that Dolphin can idle.
#
# However, because the wait for the physics update is completely
# detached from the vblanks, the game will wait even *after*
# `VIWaitForRetrace` (until one frame of lag happens: then there
# will always be at least one physics step to do after that).
# The second line skips the idle loop: this creates the conditions
# so that, from the `VIWaitForRetrace` onwards, there's always a
# physics step to take. (Thus, the loop is naturally skipped.)
#
# The main reason why this speed hack isn't enabled by default is
# that it limits the frame rate to a dividend of the vblank rate.
# Due to how demanding this game is on the Wii's CPU with default
# clock settings, the speed hack will make the game constantly jump
# between 60 and 30 FPS during a race. Thus, the wiki explains that
# the speed hack is meant to be used with an overclocked emulated
# CPU.
