After updating from Windows 11 version 23H2 to 24H2, some games may experience unstable frame rates.
If the frame rate is unstable, the game may feel sluggish or the screen may stutter.
This issue also occurred when I updated from Windows 11 version 21H2 to 22H2.

*When you turn on Auto HDR, Windowed Game Optimization is automatically turned on. If you want to turn off Windowed Game Optimization, you must turn off Auto HDR first.
