Gigapixel v6.1.0

There is a bug with Gigapixel AI 6.1.0. It is using the wrong GPU. I have 2 GPUs - RTX 3090 and GTX 1080 Ti. If I select RTX 3090 from the settings, GAI uses GTX 1080 Ti. If I select 1080 Ti, GAI uses RTX 3090. Please see attached a video I recorded. (2.5 MB)

You should also raise a support request at the main website and upload the logs. The location can be found under the Help menu.

Some funny thing happened a moment ago. I started processing, then cancelled it, changed some settings and started processing again. Now Gigapixel shows two progress bars, just like it was processing two files at once though it processes one file at a time. Not a big issue, it just looks strange :smiley:

I am getting severe artifacts in the top left corner:

Using M1 Max (same problem with CPU)


Some tiles did show up for him.

Thomas, it reminds me of the issue i have with VEAI with block compression appearing on dark part, could it be related ?

I can’t say, but it looks comparable.

These artifacts are very prominent, to the point of making this marvelous magical software basically unusable, unfortunately, in darker blue colors - jeans, etc.

I can’t be the only one with this issue? M1 Mac using GP6.1 as a plugin in current Photoshop. If I copy and paste images to new files, sooner or later Photoshop partially locks up—I can usually close and save files, but almost anything simply yields the system’s error sound. I tried in the current Photoshop beta, as well—same thing. Happens every time. Anyone else?

Thank you.

You may need to offer a explanation of what you are doing as copy and paste has nothing to do with GigaPixel.

I am suffering from a sleeping system too slow because Giga pixel v6.1.0 is using a wrong GPU !!!

The person you replied to is NOT a Topaz Labs employee, temper your language and do not threaten people here.

Have you selected the correct GPU in the preferences? Go to Help, Graphics info and press Copy then paste the info here.

Hello all,any news on the next update of this wonderful program?

Hi, I would like to try Gigapixel on 32bit .HDR images. These images are usually made with multi bracketed exposures so the .HDR captures the wide dynamics lighting of a location or scene. Then the .HDR images are used for lighting, reflections, and background plates for CGI 3D renderings. The .HDR images store the wide dynamic range in a 32bit file. So my questions is does Gigapixel v6.1 process such 32bit files ? As a photoshop plug-in can it operate in 32bit mode ?

thanks, Richard

v6.1.0 seems to blowout the brightest highlights in places.

Specular highlights (wet surfaces) can become solid white blobs that look like paint splatter when they should be somewhat transparent to the background and contain some detail.

I tried to improve Avatar The last Airbender but all models provide unsatisfactory results:


What should I do wrong?
Can anybody give me some tips?

Some free software provides much better result (eg. REAL ESGan):


If it is a video use VEAI

Yes, it’s video, but VEAI results are much worse compared to Gigapixel. So that is why I tried to use Gigapixel but without success.
