Hello, I tried launching Marbles RTX but I get this in the crashdump log:

Can anyone assist in me trying to successfully launching MARBLES? It seems it cannot be launched

I also ran into the same issue on Windows, and found that it was happening since Marbles was configured to require a minimum of 11GB of GPU memory. I found the configuration file with the setting to change the minimum GPU memory required in the Marbles installation location.

If you navigate to
<Omniverse Install Location>/omniverse/Library/marbles_rtx-<BUILD>/_build/windows-x86_64/release/apps
you’ll find a file named omni.app.marbles.kit which has a bunch of configuration options. In there you’ll find a line that says renderer.minGpuMemoryMB = 11000. You can change this to something less than this, in the case of the RTX 3080, something less than 10000 should be fine.

Minimum requirements were set knowing the Marbles experience would not be enjoyable if playing with a GPU with less than 11GB. You can certainly try playing Marbles RTX under minimum suggested specs, but frame rates will be less desirable.

I want to point out that the minimum system requirements state “VRAM: 6GB”, and the recommendation is “VRAM. 8GB” - this makes the 11 GB requirement sort of unexpected.
Beyond that, as running with less than 11GB is possible (an RTX 3080 at least somehow manages), it would be nice to have the app crash & necessary digging in log files replaced with an on-screen warning message.
