Acrobat Reader DC - high cpu usage - suddenly

[addobbator]

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

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

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

Thanks,

I have Problem that after I Checked Security (Enhanced) > "Enable Protected Mode at Startup" (to resolve error 507, Attached picture). when I open PDF Documents from Web), the CPU is Very High (25%). if I Uncheck the  'use page cache', This will solve the problem?

Thanks,

Idan.

Hi there

Please try to uncheck the 'Use page cache' option as described above and see if that works for you.

Let us know how it goes

iMac OS 13.1, Adobe Reader 2022.003.20281, cpu usage reached 99% from time to time, unchecking "use page cache" doesn't help.

Hi @matias2718 

We are sorry to hear that.

Please remove the application using the Acrobat cleaner tool https://www.adobe.com/devnet-docs/acrobatetk/tools/Labs/cleaner.html , reboot the computer once and reinstall the application using the direct link https://get.adobe.com/reader/enterprise/

Let us know how it goes.

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.

Hello, just wanted to say that Im having same problem (high CPU ussage in background).

Windows 11 Home

CPU Intel(R) Core(TM) i7-10875H

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.
