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

  • 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

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

  • This post is deleted!
  • Speed dial doesn't load sometimes. And most importantly, when I close the browser, a "Opera Internet Browser" process remains active and takes up a % of CPU.

  • Sorry for writing for a second topic, but this was my main issue that I was here for. As I explained in my previous post, I had to write this from Chrome because of a log in issue.

    I'm on :
    System:macOS Version 10.14.6 (Build 18G103) 10.14.6 64-bit

    I've disabled every ad blocker and extension.

    And only 2-3 tabs are open on my Opera; the forums tab, the extensions tab and the about tab.

    Despite this my fans has been running loud non stop for hours.

    I can normally work on multiple Opera windows and tens (sometimes over a hundred, close to 200) tabs for my work. I normally use extensions like The Great Suspender and Session Buddy to take off the load off, but I've disabled everything now. I've worked this way with Opera for many years without any problems.

    And yet, for the past few days, my fans have been going up non stop even at the smallest of actions.

    I looked at the Task Manager, the browser in total was taking up about to 1~ GB and it was normal for me. All the tabs seemed idle or taking up really small space (I don't know if I'm wording this right, this is not my main language)

    Anyway, since the fans didn't stop no matter what I did, and the macbook started overheating, I cleared every tab, removed as many extensions as I could one by one (I only had 4-5 active ones anyway), disabled the ad blockers and the fans still didn't stop.

    Then I restarted the browser, which didn't make a difference. Having 1 tab was no different than having many.

    After close to an hour, there finally seemed to be some calm, and this time I shut down the wi-fi and restarted the browser this way. This time, even though there was no connection, the fans still went up really loud for about half an hour.

    This never happened with Opera before. I don't exactly remember if there had been an update recently, but if it did could it be related?

  • Hello everyone. Updated Opera And noticed that the laptop began to use forced cooling often. Opera 74.0.3911.203, Ubuntu 20.04.2 LTS (x86_64; ubuntu: GNOME) ... htop shows that opera is loading core sometimes multiple CPU cores (ryzen 5 4600u) by 100% ... while several non-"heavy" tabs were opened ... static pages/opera_new-window.png

  • @alexdmake Probably related to the same issue everyone else is having (Windows, Mac and Linux) today with speed dial not showing and high CPU load. Since it only happens at startup and is platform-independent, it has to be something with Opera's servers - my guess is something with Sync.

  • downgraded version 74.0.3911.160 ... everything is ok

  • @sgunhouse HI,I had a problem while the browser was running a long time after launch.

  • @alexdmake They tell me there was a bad update to one of the built-in extensions. They have a new update, but you have to force it to check. Go to menu > Extensions > Extensions, enable Developer mode, and click on the Update button.

  • @sgunhouse Yes everything is OK. thank

  • I shut down the macbook last night and opened this morning; a few tabs in and all in sleep mode (i had to activate the extensions and adblockers back). Despite all of the tabs being in sleep mode, the fans are still running high. Sometimes they get really low, to the point they seem like they're going to stop, but as soon as I start working on anything small, they rise up again.

    This never happened with Opera before unless I was doing some heavy work, or had multiple apps like Adobe in the background. Right now I have nothing except Opera (and currently chrome for writing this).

    Please help!

    (And once again, I'm writing this from Chrome, because like I wrote in a previous thread, I get an error when trying to log in here from Opera)

  • The problem is now gone. Open Opera, wait few minutes and force close it. After that it should be updated. But it's crazy to waste so much time on this (migrating to other browser when that happens), so I'll just stick with the other one now, hard to trust Opera after that sh**** action.

  • @limpemu Actually it no longer crashes for me nowadays, except the occasional tab crash. It still takes up huge resources, primarily RAM, though. It is therefore difficult to say what was causing the crashes. However, I do use the Opera task manager all the time, and some tabs do cause very high RAM and CPU usage. Extensions are not the culprit in my case.

    In the case of GPU acceleration, as long as the browser doesn't crash I don't see a reason to turn it off, since it offloads some resources from the already-overused CPU. However, it's a good idea to try this if you are still experiencing crashes.

  • @alobpreis said in The High CPU/RAM/GPU Usage Topic - Opera for Desktops:

    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%.

    Without having updated Opera, this is not happening anymore, so I guess it was related to some Opera server as mentioned above or maybe a hidden internal extension.
