What Is Opera GX?
Opera GX is a web browser made by Opera Norway AS. It is based on the same Chromium browser engine used by many other browsers, but it is marketed toward gamers and includes extras like sidebar integrations, resource controls and gaming-themed features.
On Windows and macOS, the main app process is typically opera.exe on Windows and the Opera GX app bundle on macOS. If you installed it yourself from Opera's site or another trusted source, it is usually just your web browser, not a system component.
Is It Safe?
Yes, Opera GX is generally safe when it is the real app from Opera Norway AS. It is not part of Windows or macOS, so your computer does not need it to boot or run normally.
If you want to verify it, check that the file is in Opera's normal install location rather than a random temp or downloads folder. On Windows, right-click opera.exe, open Properties, then check Digital Signatures for Opera Norway AS. If the file is somewhere unusual or the signature is missing, treat that as suspicious and investigate further.
Should I Disable It at Startup?
Usually yes, if you do not want your browser loading in the background when you sign in. Disabling Opera GX at startup is generally safe. The browser will still work normally when you open it yourself.
Some browser features may use background processes for notifications, updates or faster reopening. If you rely on those, you may prefer to leave startup enabled. Otherwise, disabling it is a reasonable way to reduce background activity at sign-in.
If Opera GX is not actually listed in startup, there may be nothing to disable. In that case, any background activity is more likely coming from the browser being left open, running background apps, or scheduled update tasks.
Why Is It Using High CPU or Memory?
Browsers often use a lot of memory because each tab, extension and site can run in its own process. Opera GX can also use extra resources for video, streaming sites, chat integrations, animated themes or many open tabs.
High CPU use is often caused by a heavy website, a stuck tab, hardware acceleration issues, or an extension. If Opera GX stays busy even with few tabs open, close extensions one by one and test again. Restarting the browser can also clear a hung tab or process.
On Windows, Kudu's Performance Monitor can show whether opera.exe is the main resource user and help you identify the PID to end if the browser is frozen. Only end it if you are okay losing unsaved work in open tabs.
How to Disable or Remove It
If Opera GX appears in startup on Windows, you can disable it from Task Manager > Startup apps or in Kudu's Startup Manager. On macOS, check System Settings > General > Login Items for Opera GX or related helper items.
If you want to stop background behavior inside the browser, look through Opera GX settings for background apps, notifications or startup behavior. Setting names can vary, so use the browser's settings search if needed.
To remove Opera GX completely, uninstall it from Settings > Apps on Windows or move the app to Trash on macOS, then remove leftover login items if any remain.
Where Kudu Helps
Kudu can show whether Opera GX is actually set to start when you sign in and lets you disable that startup entry without uninstalling the browser. On Windows, it can also show boot impact for startup items.
If Opera GX is using too much CPU or memory, Kudu's Performance Monitor shows live usage and the exact process using resources. If needed, you can end the browser process by PID, then reopen it normally.
Kudu's System Cleaner can also clear supported browser caches while preserving cookies, history and passwords. That can help reclaim space, but it will not guarantee better browser performance.
Frequently asked questions
- Is Opera GX required for Windows or macOS?
- No. Opera GX is a third-party browser, not a system component. Your computer will work normally without it.
- Can I disable Opera GX at startup without uninstalling it?
- Yes. Disabling its startup entry only stops it from launching automatically at sign-in. You can still open and use the browser normally.
- Why does Opera GX have multiple processes in Task Manager?
- That is normal for Chromium-based browsers. Tabs, extensions, GPU work and other browser features often run in separate processes for stability and security.
