How to Set Ram Limit in Opera Gx - Opera GX

Open Opera GX's Settings > Performance tab, then toggle on the RAM limiter and drag the slider to your desired memory limit. Done!

Opera GX is built specifically for gamers who need their browser to play nice with system resources. The RAM limiter is one of its killer features — it lets you cap how much memory Opera uses so your games run smoother.

How to Access the RAM Limiter

Jump into Settings by hitting the menu button (three horizontal lines) in the top-left corner. Click Settings, then find the Performance section on the left sidebar. You'll spot the RAM limiter toggle right there. Flip it on, and boom — you're ready to customize.

Setting Your Memory Limit

Once the limiter is active, a slider appears below it. Drag it left to use less RAM, right for more headroom. Most gamers find sweet spots between 500MB and 2GB depending on their system. If you're running intensive games, keep it lower.

Casual browsing? You can afford more. The browser automatically respects your limit and won't exceed it — no trickery, no hidden processes eating memory behind the scenes.

Why This Matters for Gaming

Your CPU and RAM are finite resources. Every tab you open, every extension you run, every ad that loads takes a slice. Opera GX's memory limiter ensures your browser stays out of the way while you're gaming. The performance control is automatic once set — you don't have to babysit it.

Since Opera GX launched in 2019, this resource-limiting approach has become its signature move. It's why gamers love it.

Set your RAM limit based on what you're doing. Gaming session incoming? Crank it lower. Streaming research? Go higher. Simple as that.
