XnView supports Canon's Camera Raw format (CR2), but opens a file very slowly. A single 20 MB file opens for a 20 seconds!
See a process monitor log here and a sample file.
Having a 100% reproduce of that bug.

Re: ultra slow opening of CR2 files
Do you use 'embedded thumbnail' in View>Misc - Camera raw?

Re: ultra slow opening of CR2 files
No, I use full size:

If i choose embedded thumbnail, the read speed increases, but losing a quality. Is it hard to read the whole RAW instead of jpg thumbnail inside of it, but not freeze that hard? The software like lightroom or canon's digital photo professional reads the file very fast without losing a quality.

Re: ultra slow opening of CR2 files
Old topic but it would be great to have an option for loading thumb first and refresh the view after a few seconds if full size loaded (in background without freezing).
