Opera gx ram and cpu limiter do they actually work

Opera gx has been marketed as a browser built for gamers and the feature everyone talks about is the resource limiter. The idea sounds almost too good to be true. A browser that lets you cap ram and cpu usage so games run smoother in the background

Browsers usually do not work this way. Chrome takes what it wants. Firefox manages itself. So when opera gx adds visible sliders that claim to limit usage skepticism is natural

After weeks of testing across multiple games and usage scenarios the answer is clear. The limiters do work but the reality is more nuanced than the marketing suggests

What gx control is

gx control is the resource management system built into Opera GX. It includes three main tools

• a ram limiter that caps memory usage
• a cpu limiter that restricts processor usage
• a network limiter that limits upload and download speed

These controls live in the sidebar and show real time usage meters. As the browser approaches the limit the meter changes color to warn you

Opera gx does not control the operating system. Instead it limits its own behavior by unloading inactive tabs slowing background scripts and delaying tasks. This explains both why the feature works and why the browser can feel slower when limits are active

First impressions and how it feels

Using gx control feels similar to adjusting gaming hardware settings. The sliders are simple responsive and easy to understand. You do not need technical knowledge. You move a slider and the browser reacts immediately

There is also a psychological effect. Seeing ram usage stop at a fixed number feels reassuring especially for users who are used to watching browsers slowly consume more memory over time

What actually works well

The ram limiter delivers the most consistent results. When set to a fixed value opera gx stays close to that limit even with many tabs open. It does this by unloading inactive tabs from memory

In gaming this makes a real difference on systems with 8 to 16 gb of ram. Limiting browser memory reduces stutter and improves frame consistency. The fps gain is not massive but it is noticeable especially in competitive games

The network limiter also works well. Limiting background traffic helps keep ping stable during online matches. This is especially useful on slower or capped internet connections

Where the limiters fall short

The biggest downside is browser responsiveness. When ram is limited inactive tabs are unloaded. When you return to them they reload which breaks instant tab switching

The cpu limiter is less impressive. When set too low it causes video stutter voice chat issues and slower page loading. For most users aggressive cpu limiting creates more frustration than benefit

Another weakness is automation. There is no automatic gaming mode. Users must manually adjust limits each time they play or leave them enabled permanently

Real world performance testing

Testing across three scenarios unrestricted opera gx limited opera gx and an unrestricted browser shows a clear pattern

• limited opera gx uses significantly less ram
• average fps increases by roughly five to ten percent
• browser responsiveness decreases when limits are active

Lower end systems benefit the most. On high end systems with plenty of ram the gains are minimal

Who should actually use gx control

gx control makes the most sense for gamers with mid range systems who keep their browser open while gaming. It is especially useful for users with 8 to 16 gb of ram who run music chat streams or guides in the background

If you close your browser while gaming or use a high end system with excess resources the benefit will be small or nonexistent

Final verdict

Opera gx ram and cpu limiters do work but they are not magic. The ram limiter provides real improvements at the cost of slower tab switching. The cpu limiter works but is easy to misuse. Network limiting is helpful on slower connections

This is not a gimmick. It is intentional self limitation. When used correctly it delivers exactly what it promises
