Has Precaching images changed?

To precache images I normally draw them off the screen after loading them:

Class GameImage
	Field image:Image
	Field w:Int
	Field h:Int

	Method PreCache:Void()
		DrawImage (Self.image, -Self.w - 50, -Self.h - 50)
	End

But I can tell that some images are not getting precached to the GPU, as there is a slight pause before displaying them...

So I changed the Precache method to:

	Method PreCache:Void()
	DrawImage(Self.image, 100, 100)
	Cls
End

Which works better for HTML5 but for Android the slight pause is still there...

Any ideas?

Are you using texture atlases?

Yeah, a couple of them.

as far as I know, at least as far as I have noticed its the same, just draw one sprite from each atlas at least once to get it on the gpu and you should be good, if there is a pause could it be the creation of the objects/lists for the first time?

I haven't changed anything internally...

Wondering if its the size of the graphics I am using...

Background image: 1366x768
Sprites Atlas:    1224x1170
Other:
640x293
136x195
400x215
563x120
510x36
507x36
76x38
136x195
and more...

With HTML5 it does help that I "precache" directly to the viable screen than off screen. With Android I still get the stutter... I'll investigate some more tonight.

Have you tried changing the image canvas size to a power of two?
And can the device handle those image sizes greater than 1024?

Not yet, I thought Mojo did that internally?

And can the device handle those image sizes greater than 1024?

It should, but I'll check. I had one image which was 2048x2048 and the device (Motorola G) ran out of memory when loading it via LoadImage, but when I separated the image up into 256x256 via LoadAnimImage it was fine.

Thanks for the suggestions.
