Microsoft is starting to test a new firmware update for existing Xbox One, Xbox Elite 2, and Xbox Adaptive Controllers today that will bring some important improvements to existing hardware. The biggest addition is the ability to quickly switch between paired devices on an Xbox controller, and Microsoft is also adding Dynamic Latency Input (DLI) to improve input latency on older controllers.
This new firmware update includes Bluetooth Low Energy support for compatible controllers. Most of Microsoft’s existing Xbox One controllers include Bluetooth support for use on smartphones or PCs, but the controllers connect to Xbox consoles through the Xbox Wireless protocol. This new firmware will now make it easier to switch between the two, allowing the controllers to remember your Bluetooth phone and an Xbox console and quickly switch between connected devices by double-tapping the pair button.
Microsoft’s other main addition is DLI, which reduces the input latency on controllers connected to Xbox Series X / S consoles to make gameplay more responsive. The addition of DLI means any older Xbox One controller will have reduced latency with an Xbox Series S or X console, just like the latest controllers that ship with these consoles.
