[SOLVED] why is image memory usage much bigger than image?

Hi,

So i have a single sprite with one animation that has 45 650x540 frames.

outside of construct, all 45 images together are 14.2 MB.

But when i put those 45 images into a sprite in construct and add that sprite to a layout, the layout 'image memory usage' value is increased by more than 100 MB (!)

What causes this discrepancy, and how can I avoid it?

Thanks :)

The 14.2 mb is the compressed png size. That should remain the same which means faster downloads. When the game runs, the images need to be decompressed to use.

45*650*540*4 =~ 63.2 mb

Depending on the hardware texture sizes are only power of two so 650x540 may have to take up 1024x1024 which would give:

~188.7 mb

Also keep in mind there will be other memory usage needed for the renderer in general. I think Ashley made a blog about it.

Hi. You can see it here.

Thank you both!
