As you are doing a large render, scaling it down will greatly improve antialiasing.
The aa value is the aa thresshold. The lower, the more senditive it get, 0.9 ti
9 times "croaser" than 0.1. The "default" from the presets is 0.3.
A thing that can ruin antialiasing, is extreem contrast, like a white that is
"overexposed" meaning have an RGB value larger than 1 (something like rgb<5,5,5>
cliped to rgb<1,1,1> in the final image) next to something dark.
