I am running Isaac Sim 2022.2.0 inside a VM on an OVX server, using Teradici as a remote desktop solution. Working with my scene works only when using the Real-Time renderer. FPS is around 20-60.
As soon as I switch to path traced rendering, the viewport and the whole application is almost stuck, with only 0.2 FPS.
This is the output of nvidia-smi (we have a grid driver installed, as described in the Teradici docs):
