Thank you - but I cannot upgrade to this version. I am getting an info that my “license does not include this update”
How come?! I’ve paid big bucks 15 months ago…


Yeah, about that… they had no grandfathering for those of us who purchased the product when lifetime updates were still advertised, so now we have to re-buy it every year to get the newest updates. Although, 15 months ago… that may have been after the change, so you wouldn’t be included anyway.

Anyway, why is there still not a dehaloing feature in Gigapixel after all this time? Are we seriously going to pretend that halos aren’t an issue in photos and it’s okay to enhance unwanted artifacts instead of getting rid of them?


Hm I am very sure that it read “lifetime license” and I still can use the product - I was under the impression this his would include all future updates. What’s the point of a lifetime license anyway if updates are not included. Also, speaking as a customer from the European Union, software producers are bound by law to provide updates for at least two years - not in terms of features but for bug fixes since they have to provide an error free product.

This is highly dissapointing.

Will Topaz provide fixes for the bugs mentioned above for my current version? If not, this is not acceptable behavior for products sold to EU customers. :frowning:


Nope. It used to include all future updates, but now it’s only 12 months of updates then you have to “renew”.

Please! Fix the “Save Image” button disappearing. This is two versions in a row that this problem exists.

I am not sure what you are talking about. It’s on the bottom right of the window…

Pity it’s still not M1 ready. The first time it opened on my Mac Mini, it was quite slow. Subsequently pretty fast. The first time the face model appeared the counter stuck at zero and it quit. After a few seconds, it then reappeared, and downloaded the two models.

You can pay for a one year upgrade license that is well worth it. The program performance is continually being improved so even though some bugs get fixed the upgrades are not for just bugs.

The lifetime license was removed because Topaz could not continue development with new sales only. Like all software companies they need repeating income to make better products.

Right…I didn’t say it wasn’t there, I said it disappears. Save that image you have there and the button disappears making it unnecessarily tedious to say, export that image again with a different model.

I guess this is valid for Video Enhance AI too. This Program is still kind of beta so I am more than pissed that I have to pay even the software does still not work properly in 2022. :frowning:


PLEASE support transparency in PNG images. Right now, I spend more time working around the unscaled alpha channels than actually using Gigapixel. Either I have to clean up the edges myself, or I have to add a green screen background to all of my images and make my own alpha channel while dealing with color bleed from Gigapixel.

Yes, when you save the image the button disappears but just click on the results bar of the image and it comes back. I think the Save Image button goes away to show it is already processed.

After processing, if you tap in the box for the image it returns you to the editing window where you can change the model:

I think it originally was meant that way back then and I was pretty sure it was advertised (maybe accidently) with free lifetime updates when I bought it. The confusion started when Topaz begun to decline the original contract made with the people who bought the product and backwards reverse introduced different conditions to them for the future. Nethertheless Topaz produces very good products and offering a great customer support which is not an excuse per se but we are beating a dead horse when we talk about what happend to the free lifetime purchases today again I am afraid. :neutral_face:


Is the macintosh going to get an update so that the GPU rendered image is a good a the CPU created image like Windows just did or does the Mac already have that capability?

Yes I know how to get the “Save Image” button back. My point is that IT IS pointless to make it disappear in the first place. I know when the export is complete because I just clicked the button a few moments earlier. Save for someone with the memory of a house fly, I don’t need the single most useful button in the entire program to disappear to “remind” me that its done. Certainly the mere fact that it is no longer actively up-scaling with the progress bar on screen should be enough. Imagine if Photoshop or Gimp made the “export image” option disappear after exporting an image; surely there is a less obstructive way of going about things. Anyway I won’t further the point as it most likely won’t get changed.

CPU vs GPU image quality should already be the same on Mac.

I recommend getting on the Black Friday renewal cycle to save some money each year.
