Rednreding speed drastically falls when I add a third character.

I've sone some tests and with 2 characters I get 825 iterations in 10 minutes but when I increase the number of characters to 3 I got 93 in 11 minutes. Anyone got an idea as to why this happens? Is this a bottleneck problem or something like that?

    Probably because your graphics card is dropping off and you're rendering to CPU only. Too many (and too large) textures probably.

    Characters are complex models. Dropping one more in can tip your system over from GPU to CPU render, as one explanation.

    Throwing more stuff in isn't always the best way to do something if speed is the concern. It's usually going to do the opposite, and create a longer render time.

    Which Nvidia GPU are you using, how much RAM do you have and what are the rest of your computer specs?...

    I am rendering with both my GPU and the CPU, so shoul I disable the CPU entirely to avoid the tip over?

    No, you ensure that your scene fits in your GPU's VRAM. That's the only way to avoid the tip over.

    How do I do that tho? Cuz I have no idea how.

    There's a tool called "Scene Optimizer" or somesuch, as well.
