GigaPixel also as slow as a wet week (where are the models kept)

This may tie in with my question about whether I have downloaded the model files en masse or not.

Both Denoise RAW and Gigapixel are terribly slow to update and save. Both are using the CPU heavily and the GPU hardly at all, although I have asked to force GPU with High Memory usage

I am hoping I can improve this with the right models.

From time to time (not always) I am told I have a couple of GB of model files to download, for GP DN and Sharpen. IT’s as if they are not registering or something.

Thanks for any help.
