Hi,

I recently bought AP and tried processing a raw file in the Develop Persona today. After a few minutes in the Develop Persona, my mid-2012 MacBook Pro (OS: Catalina) became very hot and noisy. The only other app that was open was one Finder window. I then tried processing the same raw (CR2) file in PS Camera Raw and my computer was fine.

These are the default settings on my AP, which I didn't change: Display set to Metal, Use only integrated GPU is unticked and Enable Metal compute acceleration is ticked 

Any advice on how to fix this?

Thanks.

(Additional info: I was learning Affinity Designer the other day and didn't encounter this issue.)

Hi dee-s,

Welcome to the forums :)

My apologies for the delayed response, as we have been closed over the holiday period.

When processing RAW files, AP will use as many resources that are available in order to decode, render and develop the image - to provide the quickest RAW development time possible. This means that your CPU & GPU will be under load when developing RAW images and fan noise is to be expected.
I appreciate you mention this was not the case for PS, however we use a different RAW processing decoder and renderer from PS, so there may be a difference in how your hardware is utilised.

There are a few things to try here if you wish to reduce this load, please open Affinity Photo>Preferences>Performance then change the following settings:

View Quality: Nearest Neighbour (Fastest)

Retina Rendering: Low Quality (Fastest)

Hardware Acceleration: Untick

Restart your app when prompted, then load another RAW file. Does this reduce the fan noise from your system?
