  output DP-1 res 2560x1440@240Hz pos 0 0 scale 1 adaptive_sync on
  output DP-2 res 2560x1440@144Hz pos 2560 0 scale 1 adaptive_sync on
  

• Description:

  • I have two monitors: One with 144hz and one with 240hz refreshrate
  • Both monitors have adaptive sync capabilities
  • When moving the mouse around on the 240hz monitor, it is lagging - feels like ~48 fps
  • Moving the mouse on the lower refreshrate monitor is fine.
  • Disabling adaptive sync on the 240hz monitor fixes the issue (DP-1)
  • Interestingly, using a higher polling rate mouse (1000hz instead of 125hz) prevents the issue as well
