Muhammed_Hamed Thank you for your guide on optimizing GPU memory, it is a great help. I have a question about the LC subdivs. When are high subdiv numbers required? I have a complex airplane interior with lots of lights and small windows. Is it helpful to use a high LC subdiv number as a basis for further final calculation to keep the noise low?

Hi Micha

I suggest using 3000 LC Subdivs for interior scenes, although you need to keep an eye on GPU memory usage as LC Subdivs have a big impact on that.
If you render in higher resolution, more than 4k you can go higher than 3000 Subdivs as long as you have GPU memory to work with

Best,
Muhammed
