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.inifile, 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.
-
Test disabling Hardware Raytracing from the engine
-
And finally, please make sure that no RTSS or overlocking are enabled for your video card while working on the engine.
