Acrobat Reader DC - high cpu usage - suddenly

hi everyone,

i'm experiencing a very annoying behaviour of acrobat reader on win 10, I usually work all the day having acrobat reader always open with 4/5 simple pdf files open, about a month ago I started experiencing this problem:

 

suddenly, the cpu usage of the adobe reader process goes high, without any action or any new files opened or whatever, it just starts randomly, as you can see from this picture acreddca.PNGexpand image

more than 20% of a quad core i7 7th, causing overheat and useless fan noise. pointless

 

I can't really understand why this happens, I have the latest version installed, i always check and install updates, but nothing changes, I also performed the "repair installation" tool and I also uninstalled it completely then reinstalled.

It's very very annoying, all day it works normally then suddenly starts doing that. If i close and re-open it sometimes it keeps working normally, sometimes the problem reappears in a while.

Hi there

 

We are sorry to hear that. Would you mind sharing the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 22.1.20085 installed. Go to Help > Check for updates and reboot the computer once.

 

Also Go to Edit (Win), Adobe Acrobat (Mac) > preferences > Page Display > Under rendering, Uncheck 'use page cache' > Click OK and reboot the computer.

Amal

Hi,

 

I have the same problem on my new macbook pro M1 from 2020. I did not have this issue with my old macbook air from 2013. Everytime i open Acrobat reader dc it consumes between 15-35% of CPU. How is this possible? I have currently unticked 'use page cache' but the problem remains unchanged. When using other PDF readers the CPU usage is next to nothing. How can this be resolved?

There's no way of resolving the issue, It's now more than 2 years old and adobe does nothing to solve it. The only sollution is to use other software from other companies.

Hi,

The problem disapeared for me after a while. I ticked the 'use page cache' again and now im keeping many huge pdfs open all the time without cpu usage above 3%. It seems as it just needs time for some unclear computing with new documents (caching?) then it stops. I still havent found a better program to use anyway but it works well now.

For what it's worth, I have just encountered one case on Windows 11 where unchecking "Use page cache" in Settings (German: "Seiten-Cache verwenden") did indeed stop high CPU usage immediately (not even a restart of Adobe Reader was requried).

 

So, this is definitely worth a try.
