If you're looking for a way to boost your computer's performance, you can try enabling Windows 10's GPU hardware scheduling.This feature was added by Microsoft in the May 2020 update, and since then, many gamers have tried it to see if it helps them.However, your computer's GPU may not support it.

If you want to learn more about GPU hardware scheduling, read on as we discuss how it works, system requirements, and how to turn it on.


How does GPU hardware scheduling work?

Typically, the Windows Display Driver Model (WDDM) GPU scheduler is responsible for managing multiple processes that submit tasks to the GPU.While the GPU is responsible for rendering, the CPU is responsible for scheduling and sending these tasks to the GPU.To make this process more efficient, the CPU will submit commands in batches rather than one at a time.

This technique is called frame buffering, and it improves performance by producing better frame rates.However, this process comes at a cost, as it also increases input latency.So when you press a button, it won't have any effect until the CPU submits a new batch to the GPU.

Hardware-accelerated GPU scheduling offloads some of the high-priority tasks your CPU would normally manage to a dedicated GPU-based scheduling processor.In theory, this should take some load off the CPU and reduce input lag.

Should you enable GPU hardware scheduling?

If your computer has a low- or mid-level CPU, GPU hardware scheduling might be worth turning on.Especially if your CPU hits 100% load in some games.

If the feature isn't available to you, there are several ways to improve your PC's performance without upgrading.For example, you can disable framebuffering through in-game options or through the GPU driver control panel.This should allow you to continue playing games with good visuals on your aging computer.

In the end, the decision is yours.Don't be surprised if you decide to test with multiple games and don't see any changes.According to Microsoft, users shouldn't notice any major differences in the game.However, when checking your CPU's temperature and load, you may notice some positive changes.

What do you need to enable GPU hardware scheduling?

Because GPU hardware scheduling kicks in in 2020, you'll need a fairly new PC to use this feature.You need to be running Windows 10 2004 or newer and have a supported GPU installed on your computer.

As of this writing, only NVidia's GPUs support hardware scheduling. Both AMD and Intel are working on supporting this feature in future updates, so keep an eye out.

Once you're sure you have a compatible GPU, double-check that it's using the latest drivers.If your PC meets all the criteria, now is the time to enable the GPU hardware scheduling feature in Windows 10.

How to Turn On Hardware Scheduling Through Windows Settings

Follow these steps to turn on GPU hardware scheduling.

1. Tap Start, then go to Settings > System.

2. From the menu on the left, select Display.

3. Under Multiple Monitors, click Graphics Settings.

4. Turn on the toggle key for hardware-accelerated GPU scheduling.

5. Restart your computer.


How to Turn On Hardware Scheduling Using Registry Editor

If you can't find this option in settings, you need to enable it from Registry Editor.Here's how you can do it.

1. In the search bar of the Start menu, search for Registry Editor and select Run as administrator.

2. Navigate to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > GraphicsDrivers.

3. Find and open HwSchMode.

4. Make sure Base is set to hexadecimal.

5. Set the value data to 2.

6. Click OK to save the changes.

7. Restart your computer.


Try GPU hardware scheduling

While GPU hardware acceleration isn't available to all Windows users, you might be able to test it yourself.Using our guide, you can enable it using the Registry Editor, or turn it on from Windows 10 settings.

If you've tried multiple ways to improve your GPU's performance without success, you might also consider replacing it.
