Hey guys, I had a question about how octane handles VRAM usage. I have a 1080ti (only running one card so it is my display card as well) but on low resolution renders its only using 193Mb of my available 8.6 gigs of VRAM at roughly 1940 samples. The scenes are taking sometimes close to 15 minutes to fully render as well under PPC. Granted, I'm using daylight with post processing etc but is this normal? Is there a setting I'm missing where I can dedicate more VRAM to producing these renders quicker?
Edit** I am using the octane render inside Cinema 4d

Hi Giszmo,
don't worry, it is how it works.
The more geometry and textures you use, the more VRAM will be used. In Octane V3, the frame buffer is loaded into system RAM. in practice, the quantity of VRAM determs the complexity of the scenes that you will be able to render, not the rendering speed. Roughly 40 million polygons are equal to 8.5GB of VRAM. If you need more space for geometry, you can use the Out-of-core feature to move all the textures innthe scene intonsystem RAM.
Take in count that the complete scene needs to be entirely loaded on each GPU, so the card with less VRAM, determs the maximum complexity that you can render.
Happy GPU rendering,
