Describe the bug

When updating the games DLSS and DLSS-FG to version 310.2.1 and using Streamline version 2.7.2 with it - it induces flickering of the REF-UI.

It also seems to break/not render UI-Mods with the new C# API - specifically MHWs-YURI-Overlay. Its REF-Menu can be opened and also flickers - but the healthbars aren't rendered.

Identify the REFramework version: REF Nightly 01081 (latest)

To Reproduce
Make sure your NVIDIA drivers are updated to the latest hotfix driver, if you have G-Sync enabled, otherwise your PC will crash (NVIDIA issue) - the download can be found here.

Update the games DLSS and DLSS-FG version to 310.2.1 (Guide here or DLSS-Swapper)

You can verify your current DLSS version by running this powershell command as an adminstrator and starting your game - it will show at the bottom left and top-right current running version for DLSS and DLSS-FG.

Enable:

New-ItemProperty -Path "HKLM:\SOFTWARE\NVIDIA Corporation\Global\NGXCore" -Name "Installed" -Value 1 -PropertyType DWord -Force; New-ItemProperty -Path "HKLM:\SOFTWARE\NVIDIA Corporation\Global\NGXCore" -Name "ShowDlssIndicator" -Value 1024 -PropertyType DWord -Force

Disable:

Update the streamline files to 2.7.2 (here):

• sl.common.dll
• sl.dlss.dll
• sl.dlss_g.dll
• sl.interposer.dll
• sl.pcl.dll
• sl.reflex.dll

Just startup the game.

Only when frame generation is enabled afaik

[Vernetzt]

Similar experience after updating DLSS and Streamline files with Frame Generation enabled.

If it matters REFramework-D2D related mods seem to render fine on my end.
Haven't tried MHWs-YURI-Overlay after updating yet.

I heavily discourage you to upgrade to DLSS 4.

It has way more ghosting and looks broken around fog.
Clouds have a weird cross artifact on themy can be seen in the sky before choosing your savefile on load menu.

This is DLSS 4 perf, preset K, on 4K output (1080p internal), no framegen

The default version of the game doesn't have that issue at all.

I am not the only one
