Hi all! New to Unreal Engine. I’m running UE 5.5 on a RTX 4070TI.
I’ve been following a tutorial, but found that as I started filling out my scene this “ghosting glitch” started appearing in the viewport. It would disappear when viewing on Path Tracer mode, and would also sometimes be fixed during a restart.
However, when I went into the render I noticed that this glitch seemed to show up, with the frames all being inconsistent because it stutters and jumps in between.
Has anyone else encountered this before or found a fix? I’ve been trying to look through forums and youtube videos and testing different render settings to no avail. All my drivers are updated.
Hello there @Jobeeish! Let’s try to figure this one out.
Your ghosting issue looks very similar to other threads encountered in the community, as seen here:
As mentioned there, for most of those cases, turning off the the shadow denoiser with this command, solves the problem: r.Shadow.Denoiser 0
You may not need to fully disable the denoiser, low/medium values can be tested for best results.
Alternatively, if that change does not fix the problem, please take the following steps for your setup:
Considering that you have just moved to 5.5, please make sure both Unreal and Windows have their latest updates.
As well, update your nVIDIA drivers, make sure you are picking the “Clean Installation” option, as well as going for the “Developer” drivers, as these have more stable settings for engine work.
If your current project was on a previous version of Unreal, and its now updated to 5.5, rendering settings from the previous build could be causing a conflict. In order to reset them, please search for DefaultGame.ini file, open it wirh a notepad, and delete all settings under the header [/Script/Engine.RendererSettings]
To rule out hardware issues, in Unreal Engine, adjust your values for engine scalabillty, to ensure your equipment is not being exerted.
