Zooming issue

[DigitalShadow]

IrfanView doesn't seem to want to use more than one thread of my cpu?

I've got a Core I7 965 with HT on, so 8 virtual cores.

IrfanView will only use 12% of the total CPU time, am I missing an option to turn on multi core support?

On my dual core laptop zooming only uses 50% of the cpu, i.e. one core.

I thought IrfanView supported Multiple threads?

AFAIK that is not so. Calls that the program makes to Windows dll procedures may run on other cores but nearly all the work is done by the i_view32.exe task on a single core.

[DigitalShadow]

do you know if they will be making the program multithreaded?

[Mij]

I have no idea.
What is and is not developed is decided by Irfan Skiljan. There is no "they".

Emphasize of Multithreading Need

Hi all,

I just want to emphasize that multithreading support would not be the worst feature to implement into IrfanView.

As time goes by, everything digital grows bigger and bigger and as of today I could have needed multithread support in IrfanView more than once!

Especially for results from PNGOUT (yes I know this is a plugin) I have to wait a long time now. And this is the work performance of a 3 GHz Core2 Core I am talking about..

...just to emphasize - keep up the good work!
