Can allocate more RAM to Affinity Photo than installed

[Affni]

In the preference window it shows 32GB as allocatable RAM though I only have 16GB installed. Would be better if the program limited this option to the maximum actually available

My size agrees.

 

Maximum is 64 GB, and apparently uses disk swapping.

You are probably right - that the max Value of 64 GB includes true RAM and swap. So far I was used (in Photoshop and other programs) to adjust the RAM separately from the cache. Because the RAM setting influences how much "air" ist left for other apps. If you allocate only 8 GB RAM to Affinity Photos  you can allocate swap-space separately then you can still open huge file without affecting other apps. In the case of affinity photo you have only the choice. Example: If I want to load 36 GB of files in Affinity Photos fpr no other program is RAM left. If I load 32 GB in programs with separate swap-mangement, I could load 1GB in RAM and 31 GB in swap = leaves 15 GB to other programs. This is surely an exaggerated example. In reality you would probably have no fun to work with such a set-up.

Anyway - I was just looking for a confirmation of my assumption. So far there is no really anything I am missing in Affinity Photos compared to  Photoshop (which I had been using since 1982 before I left Adobe software )
