Some heavy pages sometimes start eating a lot of RAM and CPU here, mostly Facebook pages with videos. With Shift-ESC you can quickly see which page is the culprit. Closing that page alone solves the issue. And often reloading the same page in a new tab doesn't produce the problem again.

And regarding the RAM usage on your computer, you should go to the Details tab, right click on any column header, select columns and add the "Memory - Commit Size" column. In my experience that's the most realistic value, and a high number there will make your computer crawl. Order by that column and see what you find.

RAM usage seems normal.

Back to the issue, use shift + esc to open the internal task manager and check if there is some process using that much CPU, RAM, whatever.

By the way, version 65 is two years old, not that recent.

Usually this posed no issue on any of my PCs, which have between 16GB and 32GB of RAM.

On some occasions, I got individual page crashes, but when I reloaded the page,

it would reduce the RAM usage elsewhere and properly load the page.

However, recently, I think as of version 65 (but could have been earlier),

Opera keeps crashing all the time with high RAM usage.

I suspect it also has to do with the GPU memory, as it happens more often with GPU-intensive websites like video sites.

However, what I see directly is just that heavier RAM usage causes crashes, and a general slowdown of the system.

The frequency is about 2–3 crashes per hour.

Has anyone else experienced this?

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.

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.

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)

@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/

I found these other two posts about this issue:

I'm on :
Version:74.0.3911.203
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?
