does it have way of smoothing lines? I noticed debug window draws choppy models. Is there a setting to smooth it?
Yes, you can enable MSAA in the project display settings. However, it is resource intensive. You can search for the FXAA shader, there is a community project that does this as a post process effect and is more performant. I think both will be part of Godot 4.0 official. You can try this for now.

FXAA will also be available in 3.2.4 (it's already in 3.2.4beta3 and newer).
Antialiasing is currently only supported in 3D, not in 2D. That said, you can often use workarounds in 2D to achieve antialiasing.
