Hello Dear Fellas!

I Have been searching everywhere to try and find a solution to my problem, so far couldn’t fixed, I hope anyone in here can shed some light into the matter,

Basically I started learning UE4 (4.26.1) a week ago, and boy! it was a steep curve to learn but amazing at the same time, I’m an Architect and Visualizer, so I decided to start the UE4 Journey with a simple Interior Archviz, I am using UE4 Built-in GPU Lightmass, haven’t try the old one yet, but the issue seems that everything works fine, but when wizing around the space there are some black flickering lines appearing you can see in the video below.

The lighting only took 6 minutes to bake and as you can see looks OK on the viewport and also in the packaged version but still though dont know what could be the problem.

I used the following parameters (also baked the light with 2048/2048) but the problem persisted

[I forced all the Raytraced effects to be OFF, and also tested with all the Raytraced effects ON but the problem is still present.

I have my GPU Drivers up to date in case you wonder, Tested Nvidia Studio Drivers and the Game Ready Drivers with the same results.](https://youtu.be/RGeFgcALfds)

I hope anybody can help me with this issue, Thank you very much in advance guys!

In case you wonder my specs:

Ryzen 3900x
64Gb Ram 3000Mhz
NVME 2.0 1TB
Nvidia RTX 3090

Best.
Julio
