Valve has released its September client update for Steam, bringing several changes across areas like the In-Game Overlay, Big Picture mode, general client functionality, and more. Have a look at some of the most notable.
Starting with the In-Game Overlay, Valve improved rendering performance, which is most obvious when the performance monitor"s FPS chart is running. This applies to games using modern graphics APIs like Vulkan, D3D12, and OpenGL"s shader pipeline. The company explicitly states this fix does not impact older games that use the ancient fixed-function pipeline, since those titles do not use the modern rendering path that was optimized.
Another issue that was addressed was when you had incorrect FPS counts in some games using DLSS. Fonts and UI elements that looked fuzzy for users with display scaling over 100 percent have been fixed, as well as the DPI scaling for the performance monitor itself. The monitor also now supports CPU temperature on Windows and Linux, which on Windows requires a kernel-mode driver.
This update also brought two accessibility fixes that add a new settings menu to desktop mode. The new menu mainly introduces a High Contrast mode for better UI visibility, options for reduced motion, and UI scale controls. On top of that, the development team has annotated many UI components to improve compatibility with screen readers and other accessibility tools.
In Big Picture, the team fixed a handful of UI issues. These include the user avatar not showing up when the client starts in offline mode, and a page shift that could happen when scrolling through link buttons on a game"s details page.
You"ll now get a notification for when a trade is reversed via Steam"s Trade Protection system. The library got a new Customization tab, which allows you to set custom artwork for any game and define a custom sort title, so you are no longer stuck with the default name when organizing your collection.
Valve has added an "End of Life Alert" for macOS 11 (Big Sur), with support officially ending on October 15th, 2025. This is happening because the Steam client relies on an embedded version of Google Chrome for some features, and that component no longer works with the older operating system.
Finally, the Steam store pages have been made wider. The company increased the main column width from 940 px to 1200 px to make better use of screen space on large monitors. This change was previously only available in the Steam client beta.
