Ehi guys, I need your help. First time in unreal. When I navigate inside the viewport I got these strange glitches/flickering as if the image breaks down in some parts. I have 2x 4090 and nvdia studio driver 576.80. Thanks for your help!
Hi @simultan_xavier ,
it’s possible that the glitches or flickering you’re experiencing in the viewport are related to a known issue between Unreal Engine and NVIDIA’s 576.xx drivers. Epic published a technical note explaining that these driver versions can cause flickering and instability on recent GPUs. You can check the official article here:
There’s also an active issue reported on Epic’s bug tracker:
The solution I recommend ,and the one Epic suggests , is to roll back to a previous driver, such as version 572.83 or older. If you updated your driver through the NVIDIA app, you can use the “Reinstall” option to revert to a previous one. Otherwise, uninstall the current driver and do a clean install of an older version.
If your GPU isn’t compatible with older drivers, another option is to launch Unreal (or Twinmotion) in DirectX 11 mode. Keep in mind that this disables features like raytracing and HDRIs. To use DirectX 11, follow these steps:
-
Open the Epic Games Launcher
-
Go to the Library tab
-
Find your Twinmotion or Unreal installation
-
Click the three dots (More Options)
-
Select Manage
-
Enable the Launch Options toggle and type -d3d11 in the text field
Hope it helps!
Thanks a lot, I’ll try to update the drivers!
