Next/Previous image delay compensation

Post by Flake » Tue May 29, 2007 6:27 am

Image changing takes a while to go to next/previous image, but sometimes it goes skipping some images not even displaying them.

Does it need so much CPU to work without glitches? Cache options are enabled, but even then this delays and skipping are annoying.

Look on Google Picasa2 on AcdSee 3.0 (no any cache mention though) performance, they work perfect even with large images. And please don't say "if you like - so use them instead".

I hope it can be improved soon

Thanks

I'm experiencing something similar here, but not just on change, but rather on resize or on change in 'fit to window' mode.
and yes, asdsee 3 was doing the resize faster, but i don't know which algorithm was used there though..

Do you have tried with 'Read ahead' option?

If you disable "High quality zoom" options, speed is icreased!

So, i think the problem is relevant to this algorithm.

Also -another suggestion- "read one image ahead" options must be work backward too!... (Even more than "one" image.)

High zoom is slow and can be slower for big picture!

I vote to that: more than "one" image ahead and back!
I have 2GB of RAM, I should be able to manage more than 1. :)
