The settings are by default and 1080 only, but the script changes stuff internally and it's very volatile (I feel like it never loads all the way through)... Here it has activated the bloom while I didn't and I only loaded characters without env. And I checked the settings yesterday because I tested the script with the denoiser.
The time is also volatile and can be fast and long without changing anything to the scene and it's incomprehensible.
And finally the time depends not so much on the scene itself but more on the light, shadows and v4 outfits(why I don't know, without iray maybe).
