I am having issues with my background parallax layers rendering to slowly.

Any help would be greatly appreciated. I found a similar problem while looking for a solution that said that I should enable region on my sprite and set h/w accordingly but when I enable region my sprite disappears.

if u want the background to appear correctly, u have to set the sprite size exact same as the viewport size. im not sure if its a feature or a bug, but i found the same problem like u had. and thats how i fixed it..

#get view port size:
var ViewPortSize = get_viewport().get_visible_rect().size

#Resize the sprite to a viewport:
$BG.scale.x = ViewPortSize.x / $BG.texture.get_size().x
$BG.scale.y = ViewPortSize.y / $BG.texture.get_size().y

Didn't seem to help me, all though I could be implementing it wrong. Thank you for the suggestion though.
