Disable GPU Scheduling via Command Line in Windows 10/11 | Guide

Disabling hardware-accelerated GPU scheduling via the command line in Windows 10/11 can be done using the Windows Registry Editor command-line tool reg.exe. This requires modifying a specific registry key.

Here’s a step-by-step guide:

Steps to Disable Hardware-Accelerated GPU Scheduling via Command Line:

1. Open Command Prompt as Administrator:

• Press Win + X and select “Command Prompt (Admin)” or “Windows Terminal (Admin)”.

2. Execute the Registry Modification Command:

• Enter the following command to disable hardware-accelerated GPU scheduling: reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers" /v HwSchMode /t REG_DWORD /d 1 /f Here’s what the command does:
  • reg add is the command to add a new registry entry.
  • "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers" specifies the path to the Graphics Drivers registry key.
  • /v HwSchMode specifies the name of the registry value to be modified or added.
  • /t REG_DWORD specifies the type of the registry value (a DWORD in this case).
  • /d 1 sets the value to 1, which disables hardware-accelerated GPU scheduling.
  • /f forces the command to run without asking for confirmation.

3. Restart Your Computer:

• For the changes to take effect, you need to restart your computer. You can do this by typing the following command in the Command Prompt: shutdown /r /t 0 This will restart your computer immediately.

Explanation:

• Registry Key: The specific key HwSchMode under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers controls the hardware-accelerated GPU scheduling feature.
• Value Explanation:
• Setting HwSchMode to 1 disables hardware-accelerated GPU scheduling.
• Setting HwSchMode to 2 enables it.
• Deleting or setting HwSchMode to 0 lets the system decide based on driver and system capabilities.

Re-enabling Hardware-Accelerated GPU Scheduling:

If you want to re-enable the feature, you can set the value to 2 using:

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers" /v HwSchMode /t REG_DWORD /d 2 /f

Or simply delete the value to let the system decide:

reg delete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers" /v HwSchMode /f

Important Note:

• Modifying the registry can have significant effects on system behavior. Always ensure you have a backup of the registry or create a system restore point before making changes.

By following these steps, you can control the hardware-accelerated GPU scheduling feature in Windows 10/11 through the command line.
