fractals (more than 80 bits used - tested with
over 800bit accuracy or over 200 decimals)
- multithread support with multi-core
processors

Unzip VirtualDub to fractalus\vdub folder if you want to use
automatic movie creation feature (see help file)

Changes since 5.70:
- added option to determine how many threads are used ( can be
scaled 1 to 16 if supported by processor - current
hyperthreading quad cores like Intel 2600 can use maximum 8 threads
-Any number of processors can be used but user interface supports
currently max 16 threads)
- thumbnail images are now automatically generated (if not
previously rendered) when fractal parameterfile is loaded and
rendered
- changed deep zoom parameter file structure to allow unlimited
zooms ( backward compatible: older versions of Fractalus will not
read new version parameters but new version will read older version
parameters correctly)
- added very simple movie player for zoom movies (avi only)
- changed fractal parameter browsing default starting directory to
fractalus\gallery folder
- fixed "black spots" on some drawing modes
- fixed video "jumping" due to insufficient accuracy when deep zoom
threshold is reached (drawing modes P,Q & R only)
- fixed julia fractal download not working (program crashed
when loading julia fractal parameterfile)
-updated user interface to more colourfull style
- changed default installer directory to 'c:\fractalus'
to avoid problems with Windows User Access Control on Vista &
Windows 7 (image & data files could not be written to program
files directory without special privileges)
Changes in 5.76 beta:
- some bugfixes and changes in gui
build 15052012: removed fade-effect (not compatible with some
systems)
Quick start guide:
Zoom with left mouse click
Unzoom with right mouse click
Select palette from menu - click random button until you find good
palette
Save picture and/or as parameterfile.
For deep zooms some tips:
- Use small image size with deep zooms and use boxed zoom.
Rendering deep zooms can be quite slow.
. Turn on autosave option when rendering deep zooms.
