Hello there @PIXEL_THUNDER !

Following your summary, you do have tried almost everything with the LOD conflicts in your build. Please try the following, if it has been already tested:

  • Set all your skeletal meshes to use only LOD 0 and LOD 1
  • Remove LOD 2 and higher entirely from all problematic meshes
  • This should result in better quality than forced LODs, while keeping some control over scaling

Also, since this is mostly happening with specific setups/GPUs, you can try forcing specific rendering/streaming values, try adding the following to your DefaultEngine.ini:

[/Script/Engine.RendererSettings]
r.Streaming.PoolSize=2000
r.Streaming.MaxEffectiveScreenSize=0
