Vegas slideshow slow ? Can we switch off preloading ?

The lag on vegas slideshows starting up is proportional to the number of images, which makes me suspect that
all the images are being preloaded. A 40-image show takes 10 seconds, which is a long time. OK, maybe my host one.com isn't the fastest, but everything else runs fast enough, and back in CE4 days a 40-image show started instantly.
I think I found documentation that says vegas slideshow has parameters preload and preloadImage, but it also suggests that the default for both is false.
If TTG have changed that, could we have an option to rest them, and if not, is there some way to get the slideshows faster ?
(I've dropped my opening page to 20 images, but 5 secs is still a little to long. frozentime.se)

You could probably change that yourself by editing the Vegas code, you'll just need to know the parameter that needs setting and add it.
Here's a post that should get you started in the right direction: https://ttg-tips-and-tricks.barbeephoto … ide-shows/

Re: Vegas slideshow slow ? Can we switch off preloading ?

Thanks, that was useful and interesting, but showed me that Backlight doesn't change the default for preloading (which is false).
I tried setting the parameter to true just for fun, but saw no change (I did remember to clear the cache).
So it seems that there's something fundamentally slow about the vegas slideshow with a lot of images. Pity.

Did you clear the template cache as well (http://yoursite.com/backlight/designer/clear_cache/)?

You might have a better experience using Galleria to run your full-screen.

I also see there's a newer version of Vegas Slideshow available than the one currently included in the Theater add-on. I've opened a ticket for myself to make that update.
