when I am using Topaz Gigapixel AI (currently running 8.0.0), sometimes (maybe 1 out of 100 images) Topaz creates one (or two) weird black holes in the upscaled image.
I am mainly using Gigapixel in the batch mode, upscaling 4x times and using the “auto” settings for basic models and model settings.
The problem did also appear with previous versions 7.4.x for example)
Here is a sample of the problem:
The first PNG file is the original, the second JPG is the upscaled result from Gigapixel with artifacts in it:
Here is a screenshot from the Gigapixel interface, where you can clearly see that the original image in the top right corner is intact and the close-up preview on the left creates the artifact:
I am also experiencing the same issue when using “Standard V2”. Has anyone else been experiencing this issue and if so, what have you done to rectify it? Thank you
I noticed that you could actually see these graphical errors before exporting your image. I tried toggling the “gamma correction” on and off, and it seems the artefact disappears when it is turned off when using the Standard V2 model. Has anyone else noticed this difference?
I stand corrected, in this image, the Gamma Correction does not seem to make a difference. The only noticeable change is that with Gamma Correction on in this image, it made the graphical error slightly less noticeable.
Latest version (8.1.2). Win11, GeForce 4060, all latest drivers.
Some images are totally fine on both Low-res and Standard models.
But some (too many to be honest) are riddled with artifacts after upscale, which makes them unusable.
I’m adding examples. No artifacts are present on the original images.
Also, Low-res always(!) adds horrible grids on even colors (sky, solid color backgrounds).
It’s clearly visible, but added some brightness/contrast on the right side of the image also.
In the end I want to use Standard model but it gives artifacts - can’t use it normally.
Ok, maybe I can use Low-res model - no, it always adds grids, and sometimes artifacts - can’t use it normally.
I recently bought Gigapixel and I find it very hard to use because of this. Also tried reinstalling Gigapixel, tried switching graphic processor to CPU/GPU, nothing. Very disappointing for 100$ software.
