GigaPixel AI & Open GL

[Garnick]

I'm working with a 2012 Mac Pro 5,1, High Sierra (10.13.6) OS. I've recently checked the Topaz site for the Gigapixel AI app what would be required to run it.  I will eventually be upgrading to a Mojave friendly GPU Radeon RX 580 if possible.  That GPU is noted as being the best for Giga AI.  However, it also seems that I would have to install the OpenGL software as well in order to run the app.  My question is - has anyone been able to run Gigapixel AI without the OpenGL software installed?

I'm running gigapixel ai 4.5.0 on a 2015 macbook pro-10.13.6 with radeon R9 m370x 2048mb     It is slow, very slow even with no other programs open.
regards
Larry.

It just crawls on my 2013 MacPro “Trashcan” running Mojave as well.

+1 very slow
and it makes use of the new CPU's too- still is slow... i have a new 2019 10 core Cpu and a moderate Gpu - ATI radeon 480x
i have tried it and stick with some other ways of enlarging my photos- it brings not much improvement on already good images i find.

We have a problem that we want to look at 100 % images; while we never did or could do that in the analogue days- and never needed to do that.
Even now it only has use up until 4K- beyond that it is print- meaning about 25% is the true enlargement for viewing.

The mobile phones show that at 100% the image may look very bad- still the print looks OK
