A new test version of Windows 10 also includes new File Explorer changes.
Microsoft is planning to automatically add HDR support to more than 1,000 PC games. The software maker is now testing a new Auto HDR feature on Windows 10, which works just like it does on the latest Xbox Series S and X consoles. Enabling Auto HDR will add high dynamic range (HDR) to a large number of DirectX 11 and DirectX 12 games, as long as you have a compatible HDR monitor.
Auto HDR can be enabled in the latest Windows 10 test build (21337) released to Windows Insiders today. It should be automatically enabled, or you can toggle it in the display part of settings. Auto HDR is just in preview for now, and not all top DirectX 11 / 12 games will support it just yet. Microsoft is also working to optimize performance and fix some issues, and the company does admit “Auto HDR does take some GPU compute power to implement.”
