Opera has just released "Opera GX" and promotes it as the world's first gaming browser. Besides the game-inspired theme and the Razer chroma integration, there's a very interesting CPU and RAM limitation feature. But will it speed up your PC game?
What is Opera GX?
Opera GX is a desktop web browser for Windows PCs. Despite the name, it is a browser intended for use in games, as the Steam built-in browser works in the Steam overlay. It's also not available on game consoles like the Xbox One or PlayStation 4.
Like Opera's standard version, Opera GX is based on Chromium, the open source project that lays the foundation for the Google Chrome web browser and the upcoming Chromium-based Microsoft Edge browsers. Websites should look the same as Chrome, and you can install Chrome extensions in this browser as well.
This gaming browser is free and was released June 1
What is a gaming browser?
Do not expect Opera GX to dramatically improve your gaming performance. This browser mainly includes features designed for gamers: a game-inspired theme with Razer Chroma integration, integrated game news and offers, a twitch control panel, and sound effects from a game soundtrack designer.
The only feature that could do this Increase your performance: "GX Control": Built-in RAM and CPU delimiters that can limit the memory and CPU load of your web browser.
A gaming theme (with Razer chroma integration)
The first thing you notice is the theme: Opera GX takes off the "gaming browser" to heart and puts on a dark theme and bright colors that are typical of gaming peripherals and PCs. A quick click on the Easy Setup icon in the upper right corner of the browser allows you to select one of the few pre-selected colors or any color for the highlighting of the browser. Customizable wallpapers are also available.
This browser even offers the integration of Razer Chroma. If you enable the "Razer Chroma" option here, any color you select in the browser will be duplicated on all Chroma-enabled accessories that you own, such For example, the DeathAdder Elite gaming mouse from Razer or the BlackWidow keyboard. It's an easy way to tweak your browser theme and your RGB flash at the same time.
GX control: RAM and CPU limiter
Beyond the topic and Razer chroma integration is the most interesting feature the browser calls "GX control".
Click the "GX Control" button in the sidebar and you will get a window with a "RAM Limiter" and a "CPU Limiter". For example, you can force the browser to use only 3 GB of your system's 12 GB RAM, or limit it to 10% of your system's CPU resources.
This is a pretty unique feature. If you keep it turned on all the time, your browser will naturally slow down. However, if you do not want to manually close the tabs to free up resources for games, the limiters might be the answer.
It is of course unclear whether you will achieve an increase in performance. Windows should automatically manage resources and your browser should avoid you playing a game. However, this does not always work properly, so gamers tend to close their browser and not leave 100 tabs in the background while playing.
"Prior to Opera GX, gamers often shut down their browsers to not slow down their gaming experience. We've developed the GX Control feature that helps users run their games more smoothly without compromising on the Web, "said Maciej Kocemba of Opera.
It is also worth noting that this browser does not speed up the web games in any way. The performance features are all about avoiding the web pages and limiting the available resources.
What else does a gaming browser contain?
This browser is built for gamers. The GX Corner panel is always in the left corner of your tab bar. It contains news about upcoming games and a deals aggregator with links to the games offered. There's also a Daily Messages section that provides you with a dedicated stream of game news by default.
The sidebar has a built-in twitch control panel where you can browse the channels you follow to see who's online. You'll even get notifications when a channel you're following is live. Streaming starts.
Opera GX also plays the sound effects "GX Sound" even when you hover over icons on the "Speed Dial" page (New Tab). Opera is proud of it and boasts of "writing in collaboration with sound designer Rubén Rincón and the band Berlinist, who recently received a nomination for the original soundtrack of the BAFTA Games Award for Gris games." you can disable it.
You also get normal Opera browser features.
Opera GX also advertises several other features in Opera. For example, messengers are also available in the sidebar: Facebook Messenger, Telegram, Vkontakte, and WhatsApp are integrated, and you can chat directly through your browser's interface.
Like Opera, Opera GX also has a built-in adblocker that is free VPN and a video hiding feature that lets you play a video in a smaller overlay outside your web browser. Opera promises that a "video-over-the-game" feature will be available that allows you to watch a video walkthrough or other video about a game while playing.
Should you use it? 
If you like appearance or want features like Razer Chroma and Twitch integration, you can use Opera GX. Despite the unusual appearance, this is a pretty normal Chromium browser that should work just like Chrome does with websites.
However, this is the main attraction: the aesthetic and game-integrated features like twitch integration and gaming news. In the first version of Opera GX, the version number is even "LVL 1".
The delimiters are one of the most interesting features we've seen in a browser for some time and worth playing with. But do not expect big increases in performance. And watch out: if you keep them turned on, the browser slows down.
