how to 'weight' a DAZ scene

[lcp]

I try rendering on a GTX 960 with just 2 GB VRAM..
For my understanding I could iray-render on gpu IF and WHEN the scene takes less than these 2 GB.
I wonder where I can see how much vram my scene wants to use. How do you weight your scenes?

*additional question: right now I always look in task manager. Often I load a scene, daz takes for example 2 GB RAM, but in the second I switch viewport to Iray the RAM consumption jumps up to 6 or 8 GB.. would the same happen in the gpu vram?

It's 2Gb including everything else going on in your system. Daz itself will take a fair bit, Windows Aero uses some and having browser windows open can use a lot. It's just about possible to render something in 2Gb but not easy.

I use MSI Afterburner to show exactly how much video RAM is being used.

Haha, I never considered Aero, very well! Will try fiddling my way with afterburner and better..reading a paper comic while rendering.^^

Something we've found useful when rendering Iray on lower end cards is layering.

Rendering the image in several smaller passes and then combining the layers in Photoshop. You can achieve a lot this way, especially if your background is mostly static objects and the only thing moving are characters.

We use it to great effect.

I am using a GTX 1050 myself and rendering times are acceptable. Thinking about dimensions and finding the sweat spot of iterations necessary for a good end result work wonders when it comes to reducing rendering time. Batch rendering overnight while i sleep also works like a charm once you figure out how to set it up.

P.S: One of the first things i learned was to get rid of everything unnecessary in my scenes. Even if its not going to be rendered it will consume memory and calculation regarding light fraction, reflection etc

This! Absolutely true. If it doesn't show up in the camera, get rid of it.

Except walls, floors and ceilings. Leave those. Without them you may have some unusual things happening with light. off screen that is impacting your on camera scene.
