About Opera GX

In 2019 Opera launched Opera GX, a browser built for gamers with features that include countless customization options, sound effects, background music, a gaming-inspired design, as well as CPU, RAM and Network Bandwidth limiters that make the browser less resource-hungry and leave more of the computer’s resources for gaming. Opera GX continues to receive high ratings (4.7 out of 5.0). In June 2021, Opera GX became available on mobile devices as the world’s first mobile browser designed for gamers.
