If you open the pane (tab) called "Scene Info", you can see the number of triangles and quads for the selected item
Window->Panes (tabs)-> Scene Info
SubD you will find in Parameters Tab->General->Mesh Resolution
"View SubD Level" is the one used for Viewport and "Render SubD Level" the one used for rendering
Did another test with an empty scene.
First I loaded a simple primitive plane to determine the baseline for RAM and VRAM usage (I'm using W7 - VRAM usage on W10 is higher)
Then I loaded the Victoria 9 HD character as she comes, with no clothing and hair and rendered her with different SubD levels.
After SubD 3 the usage of RAM and VRAM start getting higher and significantly so with SubD 5
SubD 1 is the base geometry, SubD 2 divides each quad into 4 smaller ones, SubD 3 divides each of the quads from SubD 2 into 4 smaller ones etc...
I am a hobbyist at this stuff. With even more modest resources (16 GB RAM and a 6 GB RTX 2060 card in my laptop) than you, I need to optimize scenes more and more often as I buy more and more recent content. As a result, I have bought Scene Optimizer as have you but also a few other utilities the help me out with heavy scene assets as needed. Principally,

Thanks for the recommendations! I'll take a look at these tools, they might be useful to me in the future when I need to render a very heavy scene. I had purchased Scene Optimizer a few days ago, but it's good to have help from other tools that aim to optimize performance.
No one tool will be good for all cases or all of the time. Sometimes a combination of tools gets you to where you want to be. I'm on the verge of buying a desktop computer that will have more robust hardware resources than my laptop.

Useful and relevant information, thank you friend! I didn't know about SubD. This should be useful for me who is struggling with heavy scenes.
