I'm trying to figure out why sprite sheets that weigh ~ 500 kb are taking up almost 240 MB of Video RAM each. I am loading them using load when my game starts. Any help would be greatly appreciated.
#RAM Usage Sprite Sheets

Textures are uncompressed in VRAM, and those are very large textures
dapper fiber
width x height x bytes per pixel
= 3840 x 16320 x 4
= 251,658,240 bytes
= 240 MB (approximately)
According to GPT

Yes but they are mostly (like 98%) comprised of transparent pixels

Which is why they compress so well

Ok I think I see where the earlier problem was

You might want to try to reduce the size of these. If they're 98% transparent, then it seems like there's room for improvement there?

A lot of room it seems lol
About 238.5* MB in fact haha
So I guess no sprite sheets ?

That might be why the sprite sheets were taking so long to load as well ?
And causing "lag spikes"
radiant crane
probably
dapper fiber
And there's no way to load them compressed into VRAM without garbaging the image IIUC?
Problem solved it seems 😑

@radiant crane Can you use an offsetted sprite sheet (where every frame has its own offset), load the offsets to an array and have Godot change the offset during runtime ?
