Step 1: Press Win + I to open Settings.

Step 2: Navigate to System > Storage > select the drive where the game is installed > click Temporary files.

Step 3: Check DirectX Shader Cache and click on Remove files.

Fix 3: Disable Control Flow Guard (CFG)

Many users report that disabling Control flow guard of the game’s executable file can fix the lagging and stuttering issue and the game runs smoother. To do so, here are the details:

Step 1: Type Exploit protection in the search bar and hit Enter to open it.

Step 2: Select Programs settings, click the + icon next to Add program to customize, and then hit Choose exact file path.

Step 3: Navigate to the folder where your game is installed, select the DX12 executable (.exe) file, and then click Open.

Step 4: In the Program settings window, scroll down to find Control flow guard (CFG), check Override system setting, and turn it off.

Step 5: Click Apply and restart your computer.

Fix 4: Allow the Game Through the Firewall

If the game is blocked by Windows Defender Firewall, the DirectX 12 stuttering issue will happen. Then you need to allow the game through the Firewall.

Step 2: Go to the Compatibility tab and click Change high DPI settings at the bottom.

Step 1: Press Win + R to open the Run box, type regedit and hit Enter to open Registry Editor.

Step 2: Navigate to the following folder, you can copy and paste it:

 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\DWM
