Hi,
I notice that viewing/decoding of .icns and .rsrc icon files (especially the ones with 512x512 pages) can be a little slow and laggy at times even on my dual-core Windows 7 notebook. Maybe it is my weaker processor cores, maybe it is that ICNS/RSRC are not properly optimized for the Windows system as they are natively for Mac's or maybe XnView MP needs to re-acess how it decodes these files to make it faster such as:
=perhaps a knewer thread-drawing method (in the code)
=perhaps increased multi-core support specially for whenever .icns or .rsrc get viewed
=perhaps the use of a single (only 1) temporry file -although I don't like this and prefer current RAM/memory method
these are just my observation
Anyway of speeding up ICNS/RSRC icon decoding in Win?

512x512 are JPEG2000 encoded, so can be slow

In relation to this topic,
way
apparently Mac OS X 10.7 Lion added support for a 1024×1024 png icon page inside ICNS, probably worth considering for future
