CPU overload when using Affinity Designer

[xhanrahan]

It would seem that this is not a new problem?

I'm using Mac OS Catalina 10.15.5 with recently purchase Affinity designer. All was ok until recently when my computer crash due to CPU overload up to 227% which was coming from AD

Any reason to why this is happening?

Hi and welcome!

Hard to tell without knowing if with the previous Designer v1.9.0, or the actual v1.9.1 and what sort of drawing procedures you processed in Designer when you got that CPU overload.

If you are using Activity Monitor to get that number, be advised that the "% CPU" column shows the total used by all CPU cores, so for example on a 4 core CPU the max would be 400%; for a 16 core CPU it would be 1600%.

Of course, the OS will never allow any user-launched app process (or combination of processes) to use all the CPU's power. It will always reserve some for the use of essential OS processes & services.

Hi there

Thanks for the reply

AD v1.9.1 is the system. Im working on what i would consider standard graphic files, pretty straight forward. Nothing Illustrator couldn't handle for years working on the same files types without any issues? It would seem that there is an issues working with files with colour layers! because in drawing files there is no issue with working files

Does it matter that there is a big fluctuation in CPU? Any ideas to why AD is crashing my Computer?

That much is normal. What is not is if Activity Monitor shows "Not responding" for any app (Affinity included) for an extended period of time.

Thanks for your reply R C-R

Well, I'm no computer expert, so if it's normal for big fluctuation in CPU, I'm fine with that, I figured it might be the cause of the problem

However as you can see AD is not responding, basically it's freezing for up to 2 minutes or more after a command is issued, like simply selecting a layer to work on.

I'm not a heavy user, the only other application i'm using in Albeton live lite 10, which on the Activity Monitor is only using 6% max

I have de-installed and re-installed AD, doesn't make any difference?

Hi xHanrahan,

Please could you try the following beta build to see if you have the same issue? https://forum.affinity.serif.com/index.php?/topic/141623-affinity-designer-customer-beta-1942/

 

Thanks
