(3D) Poorer performance with orthogonal camera projection

Question

Hi, Ive noticed that when switching to orthogonal camera, performance drops. I get jittery camera movement. Sometimes the game freezes for a fraction of a sec. None to that happens in perspective view. Is there something in the settings I need to fiddle with?

Did you enable shadows or any kind of effects in WorldEnvironment?
It would be helpful to upload a minimal reproduction project somewhere, as this may actually be a bug.

Also, which graphics card model do you have? Which Godot version are you using? Which renderer are you using (GLES3 or GLES2)?

Hi!

I have an old AMD FirePro D300 2 GB on a Mac.
I'm using Godot 3.2 stable. GLES3.
Yes, I have fog and procedural sky on in WorldEnvironment (no dof or ssao).
No issues in perspective view, only orthogonal.
I'd share the project but it's in such shambles with dozens of subversions each testing something else, it'd be embarrassing.
That being said, I am on a Mac, so I should try rebooting as there may be a process running in the bg impacting performance (this happened before, although I'm not sure why it would impact only orthogonal and not perspective...).
