UE5.5 glicthing and flickering


Hey guys ever since i updated to the ue5.5 from the preview version , I get this problem sometimes
It usually goes away when I close the engine and open it again.

I am not a total noob , but I am really not sure how to make this go away

I would appreciate it if anyone knows or if anyone’s had this issue and was able to fix it.

Thanks a lot.

Hello there @Brusewyne1! Let’s try to figure this one out.

  • 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.

  • 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.

Hey there @Brusewyne1! Welcome to the community! This looks like the image ghosting that can come from the shadow denoiser or GPU settings as sebascova mentioned. This thread has a couple solutions. Hope it helps!

Thank you so much
that did the trick.

but now my shadows are noisy LOL

so any recommendation to get better shadows in this case ???

Thank you so much by the way

You may not have to fully disable the denoiser, I’d try lower values to see if any value can help.
