I upscaled the textures on purpose to show that crunching compression is NOT what devs should worry about. If the game freezes when loading an avatar, it’s because it has to load everything at once (shaders, audio source, lights, skinned meshes, etc…)
The VRChat devs does not allow us to optimize our avatars by enabling streaming mipmaps, LODGroup and masterTextureLimit. Those things are what the community is waiting for.
