Google's fast-track approach to updating Chrome gives a different theme to each update: last time, it was all about visual acuity. For the just launched Chrome 22 stable version, the focus swings to gaming. Web apps can now lock in the mouse control for first-person shooters, simulations and other 3D content that needs the full attention of the pointer during play. Not keen on action games through the browser? There's still some fine-tuning in place for those who live on the cutting edge, including Windows 8 users and Retina MacBook Pro owners. The update may already be sitting on your computer if you're running Chrome; if not, you can get your gaming-friendly fix (and the security notes) through the source links.
