I'm really, really behind the times, but I finally got a chance to come back to my old hobby, and playing catch up. Just installed version 4 after upgrading and it works great!
Loving the denoiser function, just wow! Thank you very much for the hard work! Now I'm curious what the heck version 2019 is and what it offers that's even better than 4, especially as I can't even imagine how this could get better
