>> it takes ~9 hours to generate ~90 seconds of audio (even on a NVIDIA V100 GPU)
btw this is true if you upsample all 3 levels. I have found in practise that you are fine upsampling 2 levels and then using a DAW to "clean up"/"remaster" [0]... again will work for certain sounds better than others.
The last upsampling step is by far the most expensive. so cutting that down cuts total time by 75%
