I have had performance issues all along with Sharpen and with DeNoise AI also. But recently I am being prompted in Sharpen Ai to download the optimized model file, when i try to use a different model on a photo. It takes forever to download only 134mb. But aside from that it also seems to be requesting the download the file each time. As in I had downloaded the model for “Out of Focus” previously and then was prompted to do it again when I opened a new photo for processing in AI. I opened Sharpen AI and downloaded all models prior to opening the most recent photo. And again it prompted me to download the model files again.
