Out of core geometry
Can I use "out of core geometry" to cover system memory without a graphics card with lots of memory?
What is the performance degradation of using system memory?
Do not you have to use a graphics card like the Titan X to do big work in the future?
Out of core geometry uses some of your system memory for textures and now, for geometry too. There is a limit to how much system memory you can use, depending on which OS you are using, and for Windows, which version also.
Depending on the scene, you may see between 50% and 30% loss of render performance when using out of core geometry. As a consequence you will want to use as much VRAM as you can, since that will be the fastest to render. The system is designed so that you can render a scene that is larger than your VRAM if you need to.
