What's the best compression method or some tips to prevent hard jittering on the first loading

[young tangle]

Hello, my whole question is in the title, I'm especially targetting a 3D game. I noticied that everyone (including myself which have a strong configuration) is having big jitter, probably caused by the loading of the textures the first time, it do not happen when closing and restarting the game.

I also noticed that when exporting on a Mac (M2) which force the ETC2 ASTC texture import, the mac have 0 jittering problems on the first launch.
I'm looking for tips for preventing this jittering to happen

Thanks 🙂

Are you preloading() your scenes/assets?

[young tangle]

Assets are directly stored in the materials / sprite nodes, and the scene is indead load using preload

And I assume this jitter happens when you first instantiate a scene?

[young tangle]

Yes exactly

There are a lot issues around this topic. Some have to do with shader compilation, some with specific nodes, I guess specific GPUs or drivers can be problematic as well. And so are texture formats apparently.

I think the first thing to do is making sure to run the latest stable version of godot. Or even the latest dev version for testing purposes and see if it was fixed already by some random commit we aren't aware of.

Then you could open a new issue on Github and hope you'll be presented with a workaround. Until it's fixed it can take a while.

A general workaround would be to simply instantiate all scenes on startup once, so stuff gets cached. This is probably the most reliable way.
