NVIDIA DGX Spark is the only officially supported aarch64 platform for running Isaac Sim at this time. Jetson-based platforms, including Thor AGX, are not supported. The T5000 GPU embedded in Thor AGX may also lack parts of the RTX feature set required by the NRD-based denoising plugin, which is likely why the rtx/nrd/PackForNRD.cs.hlsl compute shader fails to compile.​
