As a former coder I can imagine that that is the case but come on: it is 2023 now. 16 bit colours is a necessity nowadays.

Currently I am working on a huge (i.e. highly detailed) image so I am not sure Affinity is up to the task. A rough estimate for what I am working on has 2.000.000 objects. When this is finished I will have a go at Affinity on a smaller image. Hopefully I can do an export of an example to psd or something. My current experience is that it doesn't work very well.
