Opera GX comes with extra features aimed at gamers and optimizing PC performance. One example of this is the Hot Tabs Killer feature, which allows you to see which tabs consume the most CPU or RAM resources in a more intuitive way compared to Chromium's default task manager. Opera and Opera GX are based on the Chromium open source project and offer similar privacy features. Also, both Opera versions include ad blockers, block trackers and a built-in VPN.
