I get the following:

Note the 2 warnings:
2021-10-15 02:40:30 [367ms] [Warning] [gpu.foundation.plugin] Skipping unsupported non-RTX GPU: NVIDIA TITAN Xp
2021-10-15 02:40:30 [367ms] [Warning] [gpu.foundation.plugin] Skipping unsupported non-RTX GPU: NVIDIA TITAN Xp
The non-RTX GPU is the one with id 1 above, which it is understandably skipping. But why does it list these as Warnings despite me specifying –/renderer/activeGpu=2 as a launch argument? The RTX 2080 Ti is listed as the GPU with id 2 in the list that it spits out above. And, Isaac Sim launches alright as well. So, I know I got something right. Still, it’s a bit unsettling to see “Warning” messages despite following the instructions. Am I missing something?
