Valve released a Steam client update on 13 October with improved startup performance and new options for Big Picture mode. The update downloads automatically.

Big Art Mode adds a larger artwork presentation to the home screen and can be enabled under Settings > Home. The Recommended tab also gains the Personal Calendar.

Big Picture now supports screensavers under Settings > Customization. The default slideshow can display artwork from recently played games and recent screenshots. A bouncing Steam logo is the other built-in option, and custom screensavers are supported too.

The update also changes startup behaviour so the Steam main window avoids taking focus if another window was activated during startup or login, and fixes the onscreen keyboard failing to work on its first desktop invocation.
