HAGS – Hardware-Accelerated GPU Scheduling: Ultimate Guide

Hardware Accelerated GPU Scheduling Tutorial

Last updated on February 8, 2024


Hardware-Accelerated GPU Scheduling is a feature available in both Windows 10 and Windows 11 that can enhance gaming and video performance by allowing your PC’s GPU to manage its own video memory (VRAM) independently of the operating system. Let’s delve into the details and learn how to disable it if needed.

What Is Hardware-Accelerated GPU Scheduling (HAGS)?

Typically, your computer’s CPU offloads graphics-intensive tasks to the GPU for rendering. The CPU gathers frame data, assigns commands, and prioritizes them for the GPU to render. With Hardware-Accelerated GPU Scheduling, the GPU’s scheduling processor and VRAM take over this work, running it in batches to render frames. This offloads some work from the CPU, potentially reducing latency and improving overall PC performance.

Should You Enable HAGS?

If you have a supported graphics card (NVIDIA GTX 1000 series or later, or AMD 5600 series or later), enabling GPU scheduling can enhance performance during resource-intensive tasks like video editing and gaming. However, if you encounter issues after enabling it, such as app crashes or graphics-related problems, consider disabling it.

Hardware-Accelerated GPU Scheduling May Cause Some Games to Crash

Hardware-Accelerated GPU Scheduling (HAGS), while designed to enhance performance, can occasionally lead to game crashes under certain circumstances. Let’s explore why:

  1. Driver Compatibility: HAGS relies on proper communication between the GPU and the operating system. If your GPU drivers are outdated or incompatible, enabling HAGS might cause instability. Ensure you have the latest drivers from your GPU manufacturer.
  2. Game-Specific Issues: Some games may not handle HAGS well. Developers optimize their games based on traditional scheduling methods. When HAGS disrupts this expected behavior, it can result in crashes. Certain game engines or older titles may be more susceptible.
  3. Resource Allocation: HAGS allocates VRAM differently. If a game’s memory management assumes a specific pattern and HAGS changes it, conflicts may arise. Games with high VRAM demands or frequent texture swaps could encounter issues.
  4. Interaction with Other Software: HAGS interacts with various components, including DirectX, the GPU driver, and the game engine. If any of these components have bugs or conflicts, crashes may occur. Background applications (like overlays or recording software) can also interfere.
  5. Overclocking and Stability: Overclocked GPUs are more sensitive to changes. HAGS alters how the GPU operates, potentially affecting stability. If your GPU is already pushing its limits, enabling HAGS might tip it over the edge.
  6. System Variability: Every PC setup is unique. Factors like motherboard compatibility, BIOS versions, and other hardware components play a role. Some systems handle HAGS flawlessly, while others experience issues.
  7. Windows Updates: Microsoft continually refines HAGS through Windows updates. An update might introduce improvements or address existing problems. Keeping your OS up to date is crucial.


  • Test It: Experiment with HAGS enabled and disabled. Monitor game stability and performance. If crashes occur, consider disabling it.
  • Update Everything: Ensure your GPU drivers, Windows, and game patches are up to date.
  • Roll Back: If crashes persist, revert to the previous setting.
  • Community Insights: Check online forums and communities. Others might share their experiences and solutions.

Remember that HAGS isn’t universally problematic; many users benefit from it. However, if you encounter issues, weigh the pros and cons based on your specific setup and gaming habits. 🎮🔧

Enable/Disable HAGS

Method 1: Using Windows Settings (Windows 10 and 11)

Windows 10

  • Open Settings > System > Display > Graphics Settings. Toggle on “Hardware-Accelerated GPU Scheduling.” 

Windows 11

  • Navigate to Settings > System > Display > Graphics > Change Default Graphics Settings. Enable or disable “Hardware-Accelerated GPU Scheduling.

Method 2: Using Registry Editor (Windows 10 and 11)

Windows 10/11

  • Press Windows key + R to open the Run dialog.

Hardware-Accelerated GPU Scheduling Benchmarking

While HAGS does have an overall positive effect for gaming it isn’t groundbreaking. So, if you have to disable it for any reason or your hardware doesn’t support it, there is no need to have FOMO. HAGS also had very little impact on content creation performance. Below is a summary of 4 benchmarks done by gamersnexus.net, babletechreviews.com and pugetsystems.com. If you want to dive deeper into this topic, I have provided the links below.
