Optimus notebook windowed DX12 games no longer allow screen tearing [W11 22H2]

[NitroGaming]

Until recently Battlefield V with DX12 renderer and Battlefield 2042 when running in windowed mode on my notebook display with no MUX switch allowed windowed screen tearing with VSync disabled on the discrete NVIDIA GPU. This behavior has changed and these two titles act as though VSync is enabled while running windowed and the screen no longer tears. Toggling them to fullscreen exclusive acts as it should with screen tearing. Setting Battlefield V to DX11 renderer while windowed allows screen tearing as expected and works properly. Battlefield 2042 does not support DX11 and will no longer allow windowed screen tearing in DX12 as it previously did a few months ago.

I have installed Intel Graphics Command Center (Beta) to regain game profile control in order to force VSync off in these titles. VSync is disabled in the NVIDIA Control Panel. This problem occurred in the past with outdated WHQL Intel UHD drivers that Windows update installed by default on Windows 10 and was remedied by installing newer Intel drivers with no changes to the underlying NVIDIA dGPU driver. As stated DX12 windowed screen tearing previously worked properly and has recently changed, perhaps coinciding with the Windows 11 22H2 update that extended DX12 windowed screen tearing support to DX11 and DX10 titles. Windowed DX11 and DX10 screens tear as expected but DX12 no longer does.

Microsoft Windows 11 Home 22H2 [Version 10.0.22621.1194]
Acer Nitro 5 Notebook [AN517-52-52T3]
Intel Core i5-10300H
Intel UHD Graphics [31.0.101.2115]
NVIDIA Geforce 1650 Ti [528.49]
Local Flat Panel Display (1920x1080@60hz)
Single Display
Notebook plugged into AC Power.

Steps to reproduce:
1) Ensure VSync is disabled in all display drivers and individual game applications.
2) Launch Battlefield 2042 or Battlefield V (DX12 mode, not DX11)
3) Enter windowed mode using ALT+ENTER or via the options menu.
4) Look left and right with mouse and observe screen does not tear.

Hello NitroGaming.

Thank you for posting on the Intel️® communities. I am sorry to hear that you are experiencing issues when playing Battlefield V and Battlefield 2040 with your system.

In order to have a better understanding of your issue, please provide us with screenshots, or if possible, videos showing the expected behavior (Windowed DX11 with screen tear) and the issue behavior (running the games on DX12).

Is the issue present if you disable the discrete graphics and only use the integrated graphics?

Best regards,

Hello Jean,

Thank you for replying.

The issue of no DX12 windowed screen tearing is still present when utilizing the Intel UHD iGPU with the NVIDIA dGPU disabled. As an additional test I connected an external display via HDMI to bypass the iGPU entirely. DX12 windowed screen tearing was not restored with that configuration. The root cause of the issue may be a Windows 11 bug/change or configuration issue with my system. I will retest with a fresh reinstallation of Windows 11 in the future. You may close this topic.
