The latest version I have is Gigapixel AI 6.3.3 . That is the same version I have had since May of 2023. I tried Gigapixel 7.0 which still seems to be latest version and I did not like it. I didnt notice any improvement in the upscaling and the rendering time for the photos seemed to be a lot longer for some reason. So I stuck with version 6.6.3. If there is a way for you to get version 6.3.3 I would get that. If Topaz only has the latest 7.0 version available for first time buyers like you, hopefully your system is good enough that the rendering time wont be long.
As for the video upscaler, I still have not gotten it yet, but this sale might convince me to pull the trigger. Thanks for the info on that. There has been a new major update on that recently, so hopefully it is even better. But I dont think the improvement is on the rendering time, which is what they really need to work on. Most people say that if you are only talking about the quality of the upscaling, Topaz Video AI is the best video upscaler. But for rendering time, other video upscalers are better.
