XnDelayedViewMP

Post by nousername »

Hi. I feel the need to create an account for this. This is the slowest image viewer program I've ever used. First time opening after computer startup is 10-12 seconds and after that 2 seconds opening image each time even for small size picture. I tried IrfanView and it is blazingly fast but I’m not really into how that program looks. Faststone is slow, needs 1 second to open picture but XnViewMP is slower and the first startup is slowest. So far I googled there's no solution but the dev who just keep asking questions. I'm using XnViewMP latest version on Windows 8.1 64 bit for a while now. Just bearing with the issue, I still using this as my main image viewer.

I use XnViewMP on three different systems (two Linux, one Windows 10), and even after a cold reboot, opening up an image for the first time takes only a second, maybe two? After that, opening images is nearly instant.

I'm not sure what the issue might be. Perhaps Windows 8 doesn't play nice with this software? It is very odd for it be behave as slowly as you're describing.

Are you using a recent version nousername?

Some time back XnView MP was noticeably slow to open when launched, but I don't see that now, and once launched images open as winnylinny reports without any obvious delay. However, CPU power and memory access time will be factors.

One factor that affects startup time is the need to load the quite large Qt framework on which XnView MP is based, but I think Pierre may have found a way of reducing the apparent delay a while back.

Another factor that affects startup time when the program is first used is the creation of the thumbnail cache when there are a large number of images on the computer; I'm not sure whether that happens in the background, and I'm not aware of a way of disabling caching although there may possibly be one.

Can Pierre comment on the above or provide some further insight?

On some PC, there is a problem between Qt libraries and font files, this can make a slower startup. Do you have a lot of installed font?

Sorry for late reply
@cday Yes I'm using the latest version.
@xnview No, only what windows 8 brings
I tried installing 0.84 version like what other who has similar issue recommend and it was a lot faster but there is still very noticeable dalay.
