It should decrease because it runs lots of optimisations on export. How are you measuring it?

Can you produce a simple .capx for us all to test? We can then either confirm the bug or not.

Yeah, we can't debug from images, we need projects.

I have no idea - as per the tutorial I linked to, it's expected that memory use go down fairly significantly after export, maybe 25% or so.

Random shot in the dark: what's your project downscaling property set to?

Lunatrap - aha - as documented...
[quote:15npgv87]High quality: mipmaps are enabled and the spritesheet after export pads out all images to power-of-two sizes. This can significantly increase memory use, but can resolve light fringing that can sometimes occur along the borders of downscaled objects in medium quality mode. Do not use this mode unless fringing is observed, since it can use a lot more memory.
Emphasis added.

You have deliberately chosen an export mode that is documented as using more memory. Unless you see the fringing artefacts, set it to medium and the memory use should go down.

thanks a lot ashley, but still if i export at medium and even low quality... the memory is still higher than on preview

on preview 75MB

after export 90Mb

but at least is less memory than using high quality since on high it get to 112MB

another question i have... does it make sense to give the player the option to turn off / on full screen scaling quality??

does it apply on runtime??
