Changes and Improvements


  • The latest enhancement focuses on the refresh rate logic, granting the flexibility to set distinct refresh rates for individual monitors based on the content displayed. With this improvement, users can now seamlessly engage in refresh rate-dependent multitasking scenarios, such as simultaneously playing a game and watching a video on separate monitors.
  • When you have both Dynamic Refresh Rate (DRR) and Battery saver activated, Windows will maintain the lower refresh rate without switching to the higher rate until you disable Battery saver. The higher refresh rate will only be engaged after the Battery saver mode is turned off.

Fixes for known issues

  • The problem affecting certain Windows Insiders in the Canary Channel using ASUS devices or PCs with ASUS motherboards has been successfully resolved. As a result, these affected Insiders can expect to receive the respective flight update to address the issue.
  • With the installation of this build, Ethernet-connected devices will no longer experience network connectivity loss.

Prepare for the upcoming August 2023 Bug Bash, commencing on August 2nd, where we’ll be thoroughly testing the latest features from preview builds across the Canary, Dev, and Beta Channels. Keep an eye out for further information in the flight blog posts scheduled for next week. Get ready to join in and help us squash those bugs!
