Question about vid ram and how much you can do with it.

Malandar

I just built a new computer  (AMD RYZEN 7 3700X 32 gigs of ram soon to be 64 and a Geforce RTX 2060 Super with 8 gigs of memory. I wanted to go with a bigger card for more vid ram, but I got what I could afford without breaking the bank.) What I need to know , if anyone has an idea, is just how much I can put in a scene with this card, and what sort of time increase I can look at if it overloads the graphics card. Not sure if anyone can  tell me this as I am konda thinking it might vary a lot depending on what products are used. Butr I figured I would ask.

Thanks in advance.

How long is a piece of string? All this is entirely dependent on the sort of scenes you render, the geometry and mostly the texture sizes. If you are running out of VRAM then obviously you need more than 8GB.

I'm not looking for anything exact here, just general ideas...

Generally speaking, very generally, 8 Gb can handle 2 to 3 G8 characters at base SubD with a basic environment. You might have a scene where this doesn't work and you might have scenes where you can fit in another character it all depends. On what? A lot of factors, texture sizes mostly. 

What kind of time increase are you looking at if you drop from GPU to CPU? 100x? more? Enough that it is usually better to cancel and optimize the scene rather than let it run on the CPU.

Some might say 5-6 G8Fs, I've done that on 8GB of VRAM without problems but that would depend on the figure texture sizes and what else you have in the scene. If you don't need figures in the foreground you can reduce their texture sizes, or postwork them in later. All sorts of tricks to get John/Jane Does into the scene background. I use .obj figures in the DOF background with one texture map and one normal map as scene-fillers. You can put a dozen of them in the blury DOF background without taxing VRAM too much.

So somewhere between 2 and 6 G8 figures depending on outfits and textures and background. Sounds reasonable I suppose, I just have to dig out all the IRAY stuff I have bought over time now that I can use it properly now.

I managed to squeeze 5 G8 figures onto my 6gb graphics card. However, some of them technically are not wearing pants, and the one lady's bikini top has a simple cloth shader on it, the furniture had relatively simple shaders on them and the BG is an HDRi. It's all about optimization.

I have made almost all of my promos with a 1080 8GB, 16GB ram laptop without much optimization (earlier ones with a MacBookPro). WIth more complex scenes I render the 1920x1080 render in 3-4 vertical sections with spot rendering and compose them in PS. It's a bit of a hassle, but works.

...I rarely use optimisation either as I render in large resolution sizes. I currently have a 12 GB Maxwell Titan-X (dedicated ot rendering) which is pretty much up to the task, though that 3090 with 24 GB of VRAM and 10,000 CUDA cores (as well as Tensor and RTX cores and at 1,000$ less than the current Turing Titan) sure looks sweet .

At the moment 8GB goes a long way, but also depends on the resolution at which you render.

Yeah, that is probably where it is going to come back and bite me, I render at 4k mostly.

You can also render a scene in multiple layers and photoshop a scene together.

Yeah I considered a Titan one of the current 24 gig ones, but I couldn't justify the expense at the moment with my not working at the moment, so 2060 it is, I may upgrade later though depending on heo things go.

It's just good to know that I have options for making bigger or more elaborate scenes, though with 8 gigs I don't have to worry about too much I guess, not like my old 3 gig 1060... Just opened my machine with the 1060 in it and damn is it UGLY it is not all pretty like one made by Nvidia, it has nothing to make it look prety at all jsut a circuit board with a chip and a fan on it lol. (Came in the computer off the shelf HP.)

Cool, ever consider doing a few instruments that might be used in an ancient or fantasy scene?

Cool, I'll have to experiment with mine to see what I can do with 8 gigs, though I imagine with the processor I have now I could do some pretty big stuff with 3DL.
