Does Hardware-accelerated GPU Scheduling boost performance - Tested with RTX

Microsoft's Windows 10 May 2000 update is a gamechanger for PC users, bringing DirectX 12 Ultimate to the OS alongside other gaming-focused features.

Sadly, it will take a while for many of these features to have a true impact on the market; as DirectX Ultimate feature set offering gamers many of the next-generation enhancements seen in Microsoft's upcoming Xbox Series X console. Even so, we have a new feature to look at called Hardware-accelerated GPU Scheduling, a feature which will give your graphics card full control of its memory. 

With Hardware-accelerated GPU Scheduling, supported graphics cards gain more control of their inner workings. This can decrease latency and boost overall performance in specific workloads, and that's what we plan on testing today.       

To do this, we will be testing games which use the DirectX 11, DirectX 12 and Vulkan APIs with Hardware-accelerated GPU scheduling enabled and disabled to judge this feature's performance impact. 


Hardware-accelerated GPU Scheduling

With Microsoft's Windows 10 May 2020 update, support for a new feature called "Hardware-accelerated GPU scheduling" has been added, giving graphics cards full control over their own memory pools. 

This feature has the potential to enhance performance by decreasing system latency and providing more direct memory access. Support for this feature is available within Nvidia's Geforce 451.48 WHQL driver, allowing some systems to benefit from increased system performance when using supported graphics cards. 

Right now, this feature isn't supported on Radeon graphics cards. 

   Furthermore, in addition to introducing support for DirectX 12 Ultimate, the Windows 10 May 2020 Update also added a new feature called Hardware-accelerated GPU scheduling. This new feature can potentially improve performance and reduce latency by allowing the video card to directly manage its own memory.

To enable hardware scheduling, you can open “Graphics Settings: Change Default Graphics Settings”. Simply toggle the feature on and restart the system and you’ll reap the full benefits of the feature.

 

Nvidia becomes the first to enable DirectX 12 Ultimate support with its latest Geforce Driver

Maybe more of an effect can be provoked when simulating a laptop-like environment, by e.g. restricting the GPU to 8 PCIe-lanes and compare the performance theretoQuote

That's an interesting hypothesis. Definitely something that's worth investigating.Quote

No input lag tested? It would be nice to see if input lag improved under 100% gpu utilization or some situation like that.Quote

For anyone looking into a slightly more in depth explanation of exactly what this does MS wrote a blog.

While we may not see many performance differences now we can in the future as drivers get better at handling the new offloading work from the CPU. Early drivers after all and they are still going through validation and testing on MS's end. Nvidia and AMD may have the support but doesn't necessarily mean it'll do anything.Quote
