Valve’s Latest Steam Client Adds 2X-Scaling Mode on Linux, HiDPI on Windows 10

The biggest new changes of the latest Steam Client Update is HiDPI (High-DPI) monitor support for Windows 10 Fall Creators Update, as well as a 2X-scaling mode on Linux platforms that offers users high-resolution graphics and text when running the Steam Client on 4K-capable monitors. According to Valve, Linux users can force a new 2X-scaling mode by adding the “GDK_SCALE=2” environment variable to their configuration before launching Steam. To disable it, you’ll have to replace the environment variable with “GDK_SCALE=1”. The update also improves window-resizing interactions on the window manager.
