Z-fighting curves in shaded view?

[gencalp (Alperen)]

I have a very complex model. I’m working on a high-performance computer at work and still, I get weird artifacts while moving around etc. It’s like 2 surfaces z-fighting, but it only happens at surface edges. Here is a GIF of what I mean: https://gfycat.com/MessyUnlawfulHarvestmen

What could be causing this? It seems like it only happens once the model goes past a certain threshold in terms of size/geometry. I’ve also ran “ClearDrawOrder” in case the draw order was screwy, but it didn’t fix it.

I’m attaching my OpenGL settings to the post.

Hello - I’m not sure it helps here but you can try changing the setting in testZBiasFactor and see if that makes any difference. It may take some experimentation.
