BestPractice: JPG attached to model or Load WebP to Model?

I have found the Threejs Optimisation guide, and noticed basis textures was on it.

Doing the list I have gone from 4fps to 60fps+

I’m using GLB, I was going to use glb - gtlf pipeline and then use dracoloader .

Are you suggesting a client side gltf transform is better for efficiency ?
Surely I should convert the files then just use a loader for them

also, WebP animation glitch (pixel sorting) for anyone whose interested
