Just started Godot, made a simple graphics test

I'm using SDFGI and TAA for this scene, the one strange thing I've noticed is that rough metallic surfaces like that sphere can look odd, most of it is rough but there are some sharp lines, not realistic behavior for a surface like that. You can see the reflection of the sun is blurred, most of the scene is blurred, but you still get some sharp lines for some reason. This only seems to happen with roughness values between 0.1 and 0.2, a roughness value of 0 looks fine. I'm getting 210-220 FPS in this scene on a 3060 at 1080p.
