New Topaz AI High Fidelity V2 mode is super slow

When I use the new High Fidelity V2 mode the enhancement / saving is super slow. This is my screenshot after 8 minutes (2x Upscale only) and I have a very powerful MacBook…

Steps to reproduce issue:

  1. Choose Upscale 2
  2. Choose High Fidelity V2 mode
  3. Make only minor Facial Enhancements

Let me know how that goes for you and I’ll keep an eye out for your reply.

Hi John,

Sorry for my late reply. I tried your suggestions and followed all the steps but I’m afraid it didn’t work. Upscaling 2X (from 1,7MB to 2,5MB takes more than 10 minutes which seems disproportionately long. It’s also not taking up much of my RAM capacity so it seems like an in-software problem to me.

Any other tips?

Kind regards,
