Very slow CR2 support?

Post by CidelFastro »

Is xnView ever going to address the extremely poor performance rendering Canon Raw files? It's a great program otherwise

Please supply an example file and performance details XN vs other program.

Performance for NEF files is also bad and XN is unresponsive:

http://commonsarchive.org/wiki/Category ... _NEF_files (50 MiB) :shock:

NC is able to convert NEF into PNG ... but also takes some time ... "-info" is fast.
There is indeed no WinZIP under my rock.

The issue is that the program basically freezes when loading large raw files. When in the browser a folder with many raw files loads very slowly as does trying to view them usually freezing xnview
