OTOY Forums

Hi, I have 3 cards in the system, 2 gtx 690 and a 760 oven.
Octane uses 2 GB of memory 690, why he does not use 4 GB of memory 760?
The 4 GB is used only when I'm remove my two gtx 690 in setting of priority.

Hi,

This is normal.
Octane needs to copy the scene into each GPU's memory. It is too slow to access another GPU's memory so the scene is copied into each for the GPU to work on.
This means that your scene size is limited to the smallest of the GPU's that is attached.

If you want a 4GB scene size then you need to only render with the 760.

Thanks
Chris.
