AD trying to use 20GB of ram when I only have 16?

[SalfingerAndrew]

Hello, 

I've noticed when working on large projects with Affinity Designer / Photo they its sing a lot of memory/ram for example in one project, "Activity Monitor" on the Mac is saying Affinity Designer is using 20.43GB of memory when I only have 16GB?

I've attached a image below:

For this project:

the file size is 663.9 MB with a artboard size of 23822.2 px X 6585.3 px and 300 DPI

As for the Mac its:

iMac (Retina 5K, 27-inch, Late 2014), with a 3.5 GHz Quad-Core Intel Core i5, 16 GB 1333 MHz DDR3 and AMD Radeon R9 M290X 2 GB

Could it be Designer is leaking memory or is it saying to be able to run this project smoothly I need around 20GB of ram?

Here are some more images from "Activity Monitor"

Thank you for your time,

Andrew.

Hi SalfingerAndrew,

When dealing with documents with lots of images it can get quite resource heavy, so the memory gets offloaded to a temporary file on your hard drive. So whilst the application is reporting to use more memory than you have this is simply because it has been offloaded.

Note the temporary file is cleared every time you close or restart the application.

Okay, so in-order to run this document smoothly it would be recommended to have more than 23GB of memory?
