render time with forest pack pro

[EP1723]

Please help ,
I am rendering with brand new laptop I9 Alienware
The scene is not very big ,some trees and grass overlays etc.
But the rendering time is very long more than 3 hours.
I am using 3dsmax 2021 and latest Arnold render.
I have done material optimization as is by default.
What else could be done to speed up ?
Thank you

Depending what Your render, it's complexity in geometry, materials and lighting and of course- the resolution, it is not unusual for renders to exceed 5 or 8 hours.

Hi Rokas,
I am trying to render bigger image 3200x1800 and it's take 5h to finish .I probably do not have correct setting.
Can you help me to improve my render time?
Thanks

I am not an expert on Arnold, but I can try.

Feel free to send us Your scene.
