"This update ruined my ability to play games on my laptop, specifically Warzone and Apex. FPS dropped to 0 and lag everywhere," another user shared.

What is the solution?

Although it did not say, in fact, the emergency update that Microsoft released also solved the above performance issues. Now, users only need to install the Cumulative Update Preview update number KB5009596 to say goodbye to lag when playing games.
