How to avoid FPS drop while loading Texturepack?

Apollo14

Hi guys!

I've noticed that there're heavy FPS drops while creating new texturepacks:

TEST_TEXTUREPACK = TexturePack.new("images/spritesheet1.txt", "images/spritesheet1.png") --causes significant lag, FPS drops from 60 down to 40, then restores --spritesheet is not big, it's only 132kb, 1243x1542px

I've tried it with Core.asyncCall, still lags.

local function LOAD_SPRITESHEET() TEST_TEXTUREPACK = TexturePack.new("images/spritesheet1.txt", "images/spritesheet1.png") end Core.asyncCall(LOAD_SPRITESHEET)

It seems that 'TexturePack.new' is extremely heavy for some reason
(first thought was to pre-cache texturepacks but it still will cause lots of lags; and pre-cached texturepacks consume lots of ram: 10 pre-cached texturepacks of ~1mb size consume up to ~200mb ram)

TexturePack.new shouldn't be much heavier than a Texture.new, most of the time is consumed by the image decoder. Main issue is that gideros is single threaded and file loading APIs don't have an asynchronous form yet

I load all the packs at the beginning before anything starts, you could do this for maybe the 1st level graphics then load others when a bonus screen comes on or some other kind of 'natural' delay.
