Hello, @Denice
I understand that you’re experiencing issues with the Unreal Engine viewport. The flickering and ghosting you’re encountering can be frustrating. Here are some steps to troubleshoot and potentially resolve the issue:
Shadow Denoiser:
The problem might be related to the shadow denoiser.
Try disabling it by running the following command in the console:
r.Shadow.Denoiser 0
See if this resolves the flickering and ghosting.
Driver Updates:
Ensure that your GPU drivers are up to date.
Sometimes updating or rolling back drivers can address graphical glitches.
Graphics Settings:
Check your graphics settings within Unreal Engine.
Verify that the resolution, refresh rate, and other display settings match your monitor and GPU capabilities.
Viewport Resizing:
You mentioned that resizing the viewport makes the issue worse.
Avoid resizing the viewport while working to minimize the problem.
Nvidia Studio Drivers:
Some users reported that reverting to older Nvidia Studio Drivers (e.g., version 552.22) resolved similar issues.
Consider trying different driver versions to see if it helps.
Monitor Refresh Rate:
Ensure that your monitor’s refresh rate is correctly set in Windows display settings.
Sometimes mismatched refresh rates can cause visual artifacts.
I hope this info is helpful to you.
Best Regard,
Gregory Chavez
