For example the cycles renderer used in blender can't render scenes that require more RAM than a single GPU. So even adding more GPUs doesn't help, it can only be rendered using on CPU with a lot of RAM.
So the question is can I render a 30gb scene using 2x 16gb AMD GPUs using prorender ?
Hi there ,no i do not think you can do that because the prorender takes only your primary gpus memory .so it will only use one of the gpus memory which is 16gb .
The way to render the 30gb scene is to use out of core rendering which i think is a little bit slower but would still get the job done .
