Discussions about technical requirements cause my eyes to roll back in my head. Or probably they are way over my head dunno so I am just going to ask and hope someone will just answer my question and not berate me for asking. I am on a 2015 iMac running Sierra. I would like to try AI Gigapixel but don’t know if my graphics card is adequate and trying to figure it out has me to the point of saying" forget it". In a last ditch effort I am going to post the info and would appreciate it greatly if someone would give a response. Thanks so much~

Hi and Merry Xmas, the technical requirements state there are ‘unsupported’ GPUs at this link and I don’t see yours on the list…

Thanks for the reply and Merry Christmas to you too. I am questioning my actual card - if it is sufficient. I don’t find it on the unsupported list but I don’t quite understand where it might fall within the bounds of acceptable. I like playing with the actual software but the technical side of things is confusing at times.

Certainly with that card you won’t need to use CPU processing, just trial it and see how it works for you and remember that it is a final step and if you need to crop, crop the image before you enlarge it.

Thanks so much - going to give it a go!
