Hi Cabezashh,
If the power supply is sufficient, one GPU can be dedicated to the OS display while two or more GPUs can be used for rendering.
For the smoothest user experience with OctaneRender, it is recommended to dedicate one GPU for the display and OS to avoid slow and jerky interaction and navigation.
The dedicated video card could be a cheap, low-power card since it will not be used for rendering and it should be unticked (switched off) in CUDA devices in the Device Manager/Preferences.
Just like in a multi-GPU setup, it is best to have the GPU’s match in model and VRAM size. This allows multi-GPU rendering but the OS interface may still be slowed as all the GPU processing power is dedicated to the rendering process. The amount of RAM available to OctaneRender is not equal to the sum of the RAM on the existing number of GPUs, but it is restricted to the GPU with the smallest amount of RAM. It is recommended that you disable GPUs that don’t have enough RAM to allow for rendering large scenes that can fit in the RAM of the remaining GPU.
