I’m planning on building a new workstation sometime in the near future, and I’m wondering if Optix supports multi-GPU rendering. I know Cuda does, but I understand it’s a completely different process.
I have not found anything about OPTIX in blender. On the Nvidia page Optix it promotes the level of scalability, so I understand that it is supported, but without adding the amount of memory of the GPU. This means that it will use the amount of memory on the card with the least amount.
Thanks! Would NVLink combine the memory from both cards though? For example, if I have 2 RTX 3090s running in NVLink, would that give me 48 GB of VRAM?
