Its headline feature is undoubtedly the GX Control panel, which lets you define how much of your computer's CPU or RAM you're willing to let the browser use. Previously, gamers with memory-hungry browsers would have to shut them down in order to maximize their gaming experience, but with Opera GX, they can have both running at the same time.
Additionally, Opera GX has a lot of the features you'd go to the web for built in anyway, such as Twitch (integrated into the sidebar), shortcuts to sites such as Discord and Reddit, and -- like the straightforward Opera browser -- integrated messengers for Telegram, WhatsApp and Facebook.
Plus, there's no end of customization options, from a colour picker with 16 million palette possibilities, a huge suite of sound effects, exclusive wallpapers and Razer Chroma integration, so your rig elements can match your chosen highlight colors in the browser. There's also a built-in ad blocker, no-log browser VPN and an accompanying GX Corner, which will host all the latest gaming news and deals.
According to Opera, the browser's development will progress in levels. The initial early access version is designed for hardcore gamers (sign up for access here) who will also have the opportunity to have their say on future iterations -- there are feedback boxes dotted throughout the browser. A final version is planned for launch later this year.
