How to Limit Cpu Usage Opera Gx - Opera GX

Opera GX includes a built-in CPU limiter that automatically restricts processor usage, perfect for gamers who want to balance browsing with gaming performance. Here's how to enable and configure it.

Access the CPU Limiter

Open Opera GX and click the Settings icon (gear symbol) in the sidebar. Select Settings > Performance. You'll find the CPU limiter toggle at the top of this panel. Switch it on to activate resource management.

Opera GX will immediately begin limiting CPU consumption to preserve system resources for your games.

Configure Your Limits

Once enabled, you can set a specific CPU percentage cap. The slider lets you choose between conservative (25-30%) and moderate (50-60%) limits, depending on your gaming needs. Lower percentages mean more resources stay available for demanding titles. You can adjust this anytime without restarting the browser.

Additional Resource Management

Opera GX's performance optimization goes beyond CPU control. The RAM limiter works similarly—find it in the same Performance settings panel. Both tools work together to prevent browser slowdowns while you're gaming or streaming on Twitch.

Don't let your browser drain system resources. These limits take effect immediately, so you'll notice performance improvements right away. Test different CPU usage thresholds to find what works best with your favorite games.

Practical Recommendation

Start with a 50% CPU limit and adjust downward if your games experience stuttering. Most gamers find 40% provides excellent balance between browsing smoothly and keeping gaming performance steady. Check the performance panel occasionally—Opera GX displays real-time CPU usage so you can see exactly how limiting CPU usage Opera GX affects your system.
