Using the included slider, you can limit 25%, 50% and 75% of the total CPU usage. The CPU limiter, on the other hand, helps you impose limits on how much processing power the browser can use at any given time. The former allows you to limit the amount of RAM that Opera GX can use.įor example, if your PC has 8 GB of system memory, you can limit Opera GX to 2 GB, 4 GB, or 6 GB, and leave the rest for use by the operating system and video game you want to run on it afterward. For example, if you want to use your browser when playing video games (for example, go to Alt-Tab to watch a walk-through) then the integrated system resources will make a difference.Ĭlicking on the GX Control option in the sidebar will bring up a panel with two separate options: RAM Limiter and CPU Limiter.

Opera GX’s primary purpose is to give you the ability to control how much RAM and processing power is available for it.

However, right-clicking the sidebar reveals all the missing options in Opera (My Flow, Personal News, Facebook Messenger, etc.), which you can then easily activate. By default, it has fewer options this time, but with some interesting additions (GX Control and Twitch), which we’ll cover next. The extremely useful Opera sidebar also returns in Opera GX. Aside from that, you get your normal speed dial tabs (with the news feed turned off by default), which are similar to those in Opera, except for certain hover effects that you can tweak from the Easy Setup screen.
