NGX does not have DLSS feature: Issue with DLSS on Isaac

Hi,

Is DLSS expected to work with Isaac on omniverse?

I get the following error in console when starting via the isaac runscript:

2021-09-28 18:08:23 [1,103ms] [Warning] [omni.ext.plugin] [ext: omni.kit.window.viewport-0.0.0] '/home/michael/.local/share/ov/pkg/isaac_sim-2021.1.1/kit/plugins/rtx/rtx.reshade.plugin' in '[[native.plugin]]' was not found.

Best,

I get the same:

Is this error something to be concerned about? Though a window does show up for Isaac Sim, it remains unresponsive for a few minutes, with a dialog that says: “…RTX initializing…”. It does eventually become usable, but the GPU utilization (just for keeping Isaac Sim open) is a consistent 68% on my RTX 2080 Ti!
