with mobile light sources I get weird reflection artifacts when I look at them at certain angles, which I can’t seem to get rid of. I tried turning Lumen off for reflections, which didn’t help. I don’t really have any other ideas what the issue could be.
I had the same problem and it drove me crazy, i tried everything in the engine to mitigate it and nothing helped. However, the solution is very simple - you just have to install older Nvidia drivers! Try the ones from 6 months ago or so, that solved it for me
If the issue is purely visual - then your build testing should show you that it is not an issue at all…
As annoying as in sure the editor glitching out is, You should probably stick with the latest drivers for stability and deal with the fact the editor sucks…
