From my experience: moving the jan data folder before setting up GPU acceleration did not work. The option would be greyed out and hint popup states no supported GPU is present. Then after a re-install of Jan and leaving the data folder location alone, it works.
Next: after setting up acceleration I needed to create a new conversation thread. The default thread got stuck during response generation.
