.INI File Picture Cache Options
3 new INI file variables that are used by picture cache generation and
display:
• In AUD.INI:
In the [Aud] section:
EnablePicCacheThreads=1 (default)
This option creates extra background worker threads for the generation
of wave pictures when you load a project. One worker thread is
automatically created per CPU/core. Setting
EnablePicCacheThreads=0 reverts back to only using a single thread
for picture computation.
If you are running a system with multiple CPU's or cores setting this to 1
can greatly speed up the computation of pictures.
Notes:
-These threads are only active while the picture is being computed.
-This option is only applicable on multiprocessor/multicore systems.
Also in the [Aud] section:
ComputePicturesWhilePlaying=1 (default)
This option allows waveform pictures to be computed in the background
while audio playback is in progress. Most modern computers should be
able to handle this load with no problems. Note that work is only done
while new pictures are actually being computed—once the pictures are
finished rendering there is no overhead.
• In CAKEWALK.INI:
In the [WinCake] section:
ProgressiveWavePictures=1 [default]
This option enables progressive display of waveform pictures. When
enabled you will see pictures being displayed in the clips view
dynamically as they are being computed. The waveforms will update in
the background when the application is idle. If the
ComputePicturesWhilePlaying flag is set to 1, waveforms will continue
being displayed progressively even while audio playback is in progress.
This can save time waiting for a complete picture to be finished before
you can see it.
