That's too long.

Hmm, if precompressed textures help here, may be nvidias driver has problems 
compressing textures on the fly?

Can you try to short circuit SGSceneFeatures::setTextureCompression() to see 
if this helps for the long hangs?

If so we could make the use of thexture compression customizable?

Well, I am not sure what is better then. Use precompressed textures that 
cannot be read from one driver or uncompressed ones having these unacceptable 
hangs. Both is not acceptable IMO.
