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!

Hi. I have the same problem. This is log from Isaac Sim.

Hi. The error can be ignored. Isaac Sim should still work as normal.
@safdar.kureishy the “…RTX initializing…” pop-up is normal. It is compiling the shaders.
This error could be fixed in future versions of the NVIDIA GPU drivers.

Thanks for your reply. I’m trying to understand why Isaac Sim doesn’t work correctly on my computer. The problem is that typical examples sometimes run correctly, and sometimes Isaac crashes with the error VkResult: ERROR_DEVICE_LOST. And this happens haphazardly.
