Windows 10 version 2004 is the next big feature update and it
comes with useful little improvements all over the OS. For
gamers, Windows 10 May 2020 Update comes with DirectX 12
Ultimate, improved raytracing support, DirectX Mesh Shader and
various other features.
Windows 10 version 2004 is also known as the May 2020 Update
(codenamed 20H1) and the feature update is rumoured to release
on May 28, 2020.
The new update brings some useful features to users including
Cloud reset, WSL 2.0, faster performance, and as well as the
much anticipated DirectX 12 Ultimate with improved raytracing
What’s new in Windows 10 May 2020 Update for gamers
In addition to DirectX 12, Microsoft has also worked on other
areas of the OS to improve the gaming experience:
Windows 10 May 2020 Update includes the Windows Display Driver
Model (WDDM) 2.7, which should improve multi-monitor support,
enable hardware-accelerated GPU scheduling and improve video
According to multiple tests, the refresh rate on multi-monitor
setups will finally get better after applying the update.
You may have observed stuttering if you ever used multi-monitor
setup with different refresh rates for each monitor. Any window
movement between two monitors with differing refresh rates
leads to stuttering until the window movement is stopped.
The same issue can be replicated on a single monitor setup when
you run a game such as CS:GO in borderless windowed mode and
another window is running by the side. If you move another
window on Windows 10, you might notice stutters in the windowed
The problems appear to have been fixed in Windows 10 version
2004 and movements of the window between two displays do not
seem to cause any stutters.
WDDM update also adds support for hardware-accelerated GPU
scheduling and it allows GPU cards to manage their video memory
properly. This results in smoother video playback and improved
gaming experience, thanks to the reduced latency and improved
WDDM 2.7 in Windows 10 version 2004 requires Nvidia drivers
450.12, Intel driver 126.96.36.19959 and above.
Improved disk usage
The upcoming Windows 10 May 2020 Update is also changing how it
indexes for Windows Search. It includes a new algorithm that
would detect high disk usage automatically and slow down the
Microsoft also revealed that the Windows Search indexing
process will stop running when you turn on Game mode. This will
help you when you play games, update the game package and or
when the disk is being actively used.
You can turn on the Game mode feature from the Settings app:
- Select the Gaming section of the Settings app.
- Navigate to the Game Mode section.
- Click to toggle Game Mode and turn it on.
The May 2020 Update also adds support for DirectX Raytracing
1.1, which includes new techniques including inline ray tracing
and indirect execution of rays.
In version 1.1, ray tracing executions are decided at run time
and they’re not pre-defined.
The inline raytracing is more efficient than dynamic
shader-based ray tracing, according to Microsoft.
DXR 1.1 also allows game engines to load ray tracing shaders
on-demand. For example, the tracking shaders would be loaded
when your game character moves around a world and new objects
Variable Rate Shading
This is another nifty addition to let game developers adjust a
game’s shading rate in real-time. It allows the GPU to utilize
properly and it takes less toll on the GPU, which should lead
to better frame rates.
Variable Rate Shading (VRS), Mesh Shaders and Sampler Feedback
are part of the new DirectX 12 Ultimate API. If you bought a
flagship video card such as the RTX 20, you’ll be able to take
complete advantage of DirectX 12 Ultimate.
All of these changes are supported by Windows 10 May 2020
Update – also referred to as Windows 10 version 2004.
According to a leaked schedule, the May 2020 Update is expected
to be available to the general public between May 26 and 28.
