If you play on a Steam Deck, or just rock with Big Picture Mode on your PC, the latest Steam client beta will be of big interest: It adds a new "Big Art Mode" that makes your home screen look a whole lot prettier (this is a subjective evaluation, yes, but I think it's prettier), a new screensaver feature, and a range of performance improvements and bug fixes.The Big Art Mode is the big deal, so we'll start with that. Rather than the cluttered look of the standard interface, Big Art lowers the carousel of recently played games, and splashes, well, big art from the highlighted game across the backdrop. So instead of this (not the video, the image below it):(Image credit: Valve)You get this:(Image credit: Valve)It's not quite perfect: Some games, like The Merlies, don't really adapt to the system super well.(Image credit: Valve)Overall though, it's a cleaner and sexier look, ideal for those of you who prefer to keep things neat and tidy. And all the content offered through the old UI remains available, you just have to scroll down to see it now.The new screensaver option in Big Picture Mode is also entirely cosmetic but very cool. You can choose from a slideshow of art from your recently played games, with or without your own screenshots included, or a "retro inspired bouncing logo" that has the Steam logo slowly bouncing off the edges of the screen, just like your dad's old DVD player. With a little effort, you can also set up custom screensavers.Some of the less flashy stuff offered in this update is also very useful: Steam startup performance should be better following the update, the performance impact of game recording on some Direct3D 12 games on Windows has been reduced, and Linux support has been updated.It's a beta, so there's always a possibility that things could go wrong, but Valve is generally very good with this stuff so I'd say it's not too much of a dice roll. If you want to check it out for yourself, you can opt into the Steam client beta by way of the Interface menu in your Steam settings. The full patch notes for the latest Steam client beta are below.Homescreen - Big Picture ModeAdded a new 'Big Art Mode' option for the home screen. This can be enabled in Settings > Home.Added Personal Calendar to the Recommended tab on the home screenScreensaver - Big Picture ModeAdded a new screensaver feature, accessible in Settings > Customization. There are two screensavers available:The default is a game art slideshow that can be configured to show artwork from recently played games and your recent in-game screenshots.A retro inspired bouncing logo screensaverBig Picture mode can also load custom screensavers. Similar to startup movies, they can be placed in the config\uioverrides\screensavers directory in your Steam install directory (e.g. C:\Program Files (x86)\Steam or ~/.steam/root). You can use the bouncing logo screensaver (in the steamui\screensavers directory) as an example to get started.GeneralImproved Steam Client startup performance Fixed a case where after server maintenance some users might fail to auto-reconnect to SteamFixed bug where being prompted to refresh credentials more than once could trigger an immediate restartOn Windows, using the systray menu to exit while the Steam window is minimized will no longer flash the window visible brieflyDialogs that appear for serious error conditions now stay above the main windowGame RecordingFixed some cases where playback would jump to an unexpected point in the timeline when reaching the end of a play session or clipDecreased performance impact of game recording for some D3D12 games on WindowsIn-Game OverlayFixed frame rate hitches in D3D11 and D3D12 games when taking screenshots on WindowsFixed rendering the overlay and using other overlay related features (screenshots, game recording, etc.) in Vulkan games that create multiple windows.Big Picture ModeAdded explicit warning text to power menu confirmation dialogs when proceeding will shut down an active gameUpdated default artwork when an app does not have library or hero artworkReorganized the idle timer settings when on battery and AC powerSteam InputImproved CPU performance at runtime and in configuration loadingAdded information about which configurations are compatible in the configurator browser when using a game that requires Steam Input APIFixed the controller support widget showing "This game doesn't support controllers" for unreleased games that don't have controller support information yetFixed controllers not using the desktop configuration on the desktop UI login windowAdded the missing settings for adjusting emulated joystick adaptive centering on trackpadLinuxImproved download speeds on high latency connections.
