I'm a not of friend of MS-Word, because other things are from my point
of view are not as good as in openoffice/libreoffice (and I'm now
mostly a Linux user), but performance of graphic displaying in such
cases was also using slower computers than I'm now using much better
in MS-Word since version 2003 (before it was also a desaster).

Has anybody an idea how to improve performance for raster graphics?
E.g. I would like to know if Is there a raster format, which
libreoffice likes very much and can display faster? Are the links the
problem? And if, why?

I know Scribus is much faster, but I need also lot of text
functionality I have in writer.

Thanks for good ideas and bye,


Try increasing your graphics cache.

You can find it in the options dialog under memory.

Also personally I do not insert draft images into a writer document then continue editing. Maintaining the source document, link and graphics program in memory while changing the image is just increasing your load and asking for problems.

You should edit your images directly. Turn off all the other programs while you are doing it. If you need to review what you are doing I sometimes create a PDF of the source document and review that - because the images are all compressed it occupies less memory.

Have you tried using the JPG format? Make you images twice the size you need them. Once you scale them down I promise you will not detect any difference between your TIFF or PNG files.
