First of all, great work so far!
I’m running Create 2021.3.0 Beta on Arch Linux, nvidia driver 465.31.
RTX Viewport set to RTX Real-Time lacks anti-aliasing and the viewport is jittering - looks like a classic TAA jitter.
Looking at the logs:
2021-07-17 03:22:16 [Warning] [omni.ext.plugin] [ext: omni.renderer-rtx-0.0.0] Failed to load plugins, folder doesn’t exist: ‘/home/bart/stuff/omniverse/pkg/create-2021.3.0/kit/extscore/omni.renderer-rtx/bin’.
2021-07-17 03:22:16 [Warning] [rtx.postprocessing.plugin] NGX does not have DLSS feature. Check nvngx_dlss.dll is available.
I’m not sure about the plugins warning, but it looks like DLSS is not shipped or cannot be found - it seems to be looking for a DLL, which is obviously wrong on Linux.
RTX Path Traced is properly anti aliased.
It works great otherwise, hopefully you can fix the DLSS on Linux.
