Opera GX Overview
Opera GX is a gaming-oriented version of the Opera browser for Windows and macOS, built on Chromium. Its signature features are resource limiters — you can cap how much CPU, RAM, and network bandwidth the browser uses so it does not compete with a running game — along with a customizable design, sound effects, and themes, plus a 'GX Corner' hub for gaming news and deals. It includes a free built-in VPN, ad blocker, and messenger/social sidebar, and supports Chrome extensions through its Chromium base. A 'hot tabs killer' shows which tabs are using the most memory and CPU so you can close them quickly, and the GX Control panel keeps all of these limits and tools in one place. The full offline installer contains the complete browser and installs without a connection, which suits setting up a gaming PC or keeping a known-good build. This page points to the genuine Opera GX source from Opera, not a third-party host.
