Hello, are you accounting for parallax and for atmospheric refraction?

Ventura 13.4.1, I ran the benchmark again and got 3660, minimal or negligible stutter noticed with the playing card signs. I guess I will be contacting Apple Care soon regarding this.

M1 Max here, 32-core GPU, Safari 16.5.1

I agree, also there is the risk of installing a malicious add-on, specially if it is not hosted by Mozilla.

I will check them out, thanks.
