Maxwell Render 5.2 not using all 4 of my RTX 3090 GPUs
Posted: Thu May 19, 2022 2:49 am
When I inspect my GPU performance in the Task manager, Only 2 of my 4 GPUs are being used to GPU render (NOT Maxwell Fire interactive render, but Maxwell Render).
The 2 GPUs that are rendering are only using less than 15% of the GPU each.
1) Why is Maxwell nor using all of my GPUs to render?
2) Why is Maxwell Render using less than 15% of my GPUs?
