Affinity designer slowing

Recommended Posts


Theses recent days i saw that Affinity designer is slowing down, it became hard to use it. I saw others users experienced the same thing

Can someone tell what is the problem and if someone fixed it?

I download an older version (1.6) and it works as before but theses recents days with newer versions it is slowing and hard to use.

Thank you for the help

In order to get assistance you need to specify which OS you are using, Mac or Windows. Some specifications about the computer would also help. What sort of graphics card and how much RAM is available. Are you using a network to store the files or are they on internal or external drives would also be useful information.

MacBook Pro (13-inch, Mid 2012) Mac OS 10.12.6 || Mac Pro (Late 2013) Mac OS 11.7

Affinity Designer 1.10.5 | Affinity Photo 1.10.5 | Affinity Publisher 1.10.5 | Beta versions as they appear.

I have never mastered color management, period, so I cannot help with that.

What is strange to me is that i didn't had this problems few weeks ago so i am wondering if it is a general problem faced by a lot of users or something else.

You could try examining your Designer Preferences, and in the Performance section see if Hardware Acceleration (OpenCL) is enabled. If so, disable it and see if that helps.

You have 16GB but have told Designer to only use 8GB

If Designer is having to swap out pages to disk this will cause it to be slower 

In the first instance, max the slider to the far right to see if this helps any


Warp will also slow things down, so only use that for testing purposes not as a final solution

Thank you for your help but nothing changed. What is strange it is that when i downgrade to 1.6, it works fine as before but when i start to upgrade to others versions it slow down. 

In the apps performance settings if you try changing the View Quality dropdown does the performance improve at all or is it still just as slow? Does the app still perform slowly if you save and close your current file then start a new blank one and place some quick shapes?


Please tag me using @ in your reply so I can be sure to respond ASAP.

What i tried to fix the issue according the suggestions of the members of the forum and the Affinity designer member team. But i'm still facing a slow performance

- Disabled OpenCL

- Removed Symbols from the document

- Closed the Asset panel

- Reinstalled GPU driver

- Changed the view quality to Nearest neighbour

- Updated to the version


Any working solution?

Thank you

  • 1 month later... - Was facing performance problems but drawing in vector. TitanX 32Gb Ram, Xeon Server core. tried it on AMD Threadripper, 32GB RTX, Top range RTX Founders eGPU same problem. Slow on pen tool. Same file used to be fine on the previous version. AD has been the tool of choice for years. Odd that it's started to slow down now. So switched to outline view. The problem... a group that had far too many vector ploygons that was created as a shader pattern. So AD was trying to handle way too many vector objects. Solution - Rasterize and trim but kept a backup of the original vector texture just in case. As soon as the texture part was rasterized - AD was back to normal.

So, a feature suggestion: If possible, it would be great to have a vector node threshold warning saying that the document has too many vector vertices / lines.

Also would be create to have a distance count on a vector line, but that not related to this discussion.
