Pixelated window in render

[Ricardoov]

Hi. This is my first post. I was working on a render for a small conference room with some windows a the back but Im having trouble making the windows and the trees look not-pixelated.


Im using only exterior light. When I try to use interior light the room gets too dark. I'm not sure what I'm doing wrong.


Here is the render:

Thanks in advance to anyone that can tell me whats going on 🙏🏽

What is your quality setting at? Do your interior lights actually have lights in them? Are you rendering locally or in the cloud?
