The High CPU/RAM/GPU Usage Topic - Opera for Desktops

  • @federal-kaz
    Same here
    after Update 74.0.3911.203

    the browser starts now after reinstall but takes forever to load the sites
    they work but much delayed in loading

  • Guys, check 'Addons "Cashback Web Monitor"' thread, probably the same issue you have.

  • @federal-kaz Check Opera's task manager to see which process is using that much CPU.

  • @leocg I read the section about Cashback Web Monitor. As I understand it, there is no solution? Give up the opera and move on to another? I have been using it for 15 years

  • This started maybe an hour ago. I noticed one of the opera.exe processes was using 25% of the CPU (4 cores), so I closed probably "heavy" pages, but nothing changed. Opened Opera's task manager, and only thing using the CPU is the browser itself with 100%. So I close Opera and that single opera.exe process remains in memory, still consuming 25%.
    I cannot open Opera again without killing that exe first. Every time I open the browser that process uses 25% and stays until I kill it. I disabled all extensions, closed all pages from my session and this is still happening. If I kill the process with Opera open, everything is shut down.
    It's the most current version (74.0.3911.203), which has been running for some days now, so it's pretty strange. This is on Windows 7 x64 by the way.
    I checked some other topics, I tried disabling the Cashback flag, but that didn't help.
    For the record, I've been an Opera user for many many years and I don't recall this happening in the past.

    Thanks!!

  • I left it open just to try, and after 20 minutes it stopped! So I took a leap of faith... closed Opera, opened it again, but no luck, the process is back at using 25% CPU... 😞

  • Not just you. Happening to me and several of my clients that use Opera.

    Last straw for me, between this and the Cashback crap they recently snuck onto our systems I am moving on. Very disappointed since I really like Opera, but my browser is "mission critical" and I can't have this kind of stuff always happening. Good luck.

  • @alobpreis Same for me! One core loaded 100%.

  • Furthermore, lately it's been randomly using high amounts of CPU and starting to eat up RAM extremely fast, mostly on a Facebook tab. It just happened a minute ago, I closed Opera but all the processes remained, especially the one that was eating like 6 GB of RAM. I tried to kill it, it wouldn't let me, and seconds later finally most of the processes disappeared, except the 25% one I created this post for.

    Here's a screenshot of what happens:

    Opera high CPU and RAM usage

    The first time was when after closing the processes remained, the second one fortunately Opera closed more quickly.

  • i have the same problem 😞

  • Same here. After startup opera maximizes single core usage, and after few minutes it drops to normal.

  • Something similar is happening to me since this afternoon . And now, when I reopen Opera, Speed Dial is empty. I also try to save the bookmarks but I touch save and they are not saved.
    All very strange because web browsing is working.

    Opera 74.0.3911.203 in Windows 7 x64

  • All of a sudden, after a couple of years of use, Opera has started hogging CPU for no apparent reason. In the task manager, no tab is misbehaving, 3% is the highest one, but the browser CPU remains over 100% consistently, as soon as I start it up. I have disabled all extensions, toggled hardware acceleration and tried other fixes I found here, but they don't work for me. Any ideas? This renders the browser unusable.

  • I have same problem after today update . My cpu spikes for couple seconds without any reason only when i watch streams alt text

  • The high CPU load is caused by Opera itself according to the Opera task manager (Shift + ESC). Every now and then the CPU load rises up to abnormal height for several minutes and drops back to normal after it and rises again after a while and so on. I first recognized it today because my CPU fan turned on.

  • @ynhockey Did any of the suggestions by @burnout426 help? Opera is crashing daily now, causing my computer to slow down to a standstill until I end it using Task Manager. At that point, it is using 98% of my computer's memory.

  • @vilnai Yep, I see that too, they changed something today and Opera is currently useless. More reports here https://www.reddit.com/r/operabrowser/comments/m1gck6/am_i_the_only_one_whose_speed_dial_just_doesnt/

  • @federal-kaz same problem here after the newest update
