Enable Hardware-Accelerated GPU Scheduling via Regedit

Hardware-Accelerated GPU Scheduling (HAGS) is a Windows feature that reduces latency and improves gaming performance by allowing the graphics card to manage its own video memory directly. While typically toggled in the Windows Settings app, you can also force-enable or configure HAGS using the Windows Registry Editor. This guide walks you through the exact registry keys, values, and steps required to enable this feature via Regedit.

Prerequisites

Before editing the registry, ensure your system meets the following requirements: * Operating System: Windows 10 (version 2004 or newer) or Windows 11. * Graphics Card: NVIDIA GeForce GTX 1000-series / AMD Radeon RX 5000-series or newer. * Drivers: The latest graphics driver installed from NVIDIA, AMD, or Intel.

Step-by-Step Guide to Enable HAGS via Registry

1. Open the Registry Editor

  1. Press Windows Key + R to open the Run dialog.
  2. Type regedit and press Enter or click OK.
  3. Click Yes if prompted by User Account Control (UAC).

In the Registry Editor address bar at the top, copy and paste the following path and press Enter:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

Alternatively, manually expand the folders in the left sidebar to reach the GraphicsDrivers key.

3. Create or Modify the HwSchMode Value

  1. In the right pane, look for a DWORD value named HwSchMode.
  2. If HwSchMode does not exist:
    • Right-click an empty space in the right pane.
    • Select New > DWORD (32-bit) Value.
    • Name it HwSchMode and press Enter.
  3. Double-click HwSchMode to edit its properties.
  4. In the Value data field, set the value according to your preference:
    • 2 = Enabled (Hardware-Accelerated GPU Scheduling turned ON)
    • 1 = Disabled (Hardware-Accelerated GPU Scheduling turned OFF)
  5. Ensure the Base is set to Hexadecimal, then click OK.

4. Restart Your Computer

Registry changes affecting display drivers require a system reboot. Restart your PC to apply the changes.

Verifying the Change

To verify that HAGS is active after restarting: 1. Open Settings (Windows Key + I). 2. Navigate to System > Display > Graphics (or Advanced graphics settings in Windows 10). 3. Click on Change default graphics settings. 4. The toggle for Hardware-accelerated GPU scheduling should now be set to On.
