Low usage of multiple GPUs

Hi,I found that when running the same demo, I used a 3080 and its usage rate could reach 100%, and the animations ran very smoothly. When I use two 2080Ti, one has low usage and the other is 0, I have disabled SLI globally. Can you tell me the reason

The demos are not setup for multi GPU, so always you will be only using one GPU. but it’s strange that you get 100% on the 3080. please do one nvidia-smi before running Isaac Sim, and one while demo running and compare
