Hey there @_X_43! Welcome to the community! This visual artifacting is way more intense than I regularly see. I’ve seen some graphics drivers being outdated causing this to occur from time to time. So I’ll run the usual set of questions and see if we can find anything.

  1. May we to check the specs of the laptop?

  2. Are your video drivers updated?

  3. Try verifying the installation in the launcher

Hi @_X_43,

I’ve seen several people with laptop GPUs having these UE5 issues. It seems that running DX11 instead of 12 might fix it. (Project Settings → Default RHI → ‘DirectX 11’) But be aware that you will no longer be able to use Nanite.

If that does end up fixing this, please try and switch back to DX12 once 5.1 preview is released and let us know if this is still a problem.

Cheers

Something that I would also suggest is to get the Studio Drivers for your GPU, and also go to Nvidia Control Panel and make sure that you add a new rule for UnrealEditor.exe and set the power management to Maximum Performance. I remember I had similar issues when it wasn’t set to that, because the GPU would downclock thinking it’s not needed

Thanks for following up. I submitted a bug report and the QA team is aware of this problem. It was not clear if this will be fixed for 5.1.0 release though. The advice for now is to keep GPU drivers up to date as this may be something that Nvidia needs to fix.

Hi,

I switched to Direct 11 in project settings which fixed this issue and then switched back to Direct12 with no further issues.

Hi guys, this fix actually only lasted as long as the session. Two other possible fixes are to use an external monitor or try turning off GSync.
