Both cards are shown (gv100 is default card / connected to monitor), however if nvidia-settings is ran the user can see the order get flops (TITAN RTX becomes gpu 1 and gv100 gpu 0)

Omniverse will successfully launch with the following cmd:
./omniverse-launcher-linux.AppImage --no-sandbox (also tried with --no-windows flag)

Once omniverse loads and the user selects Create, the program begins to load then eventually produces the following error codes:

2021-09-10 19:06:41 [15,828ms] [Error] [carb.python] RTX engine creation failed. RTX renderers in viewport will be disabled. Please make sure selected GPU is RTX-capable, and GPU drivers meet requirements.
2021-09-10 19:06:42 [15,870ms] [Error] [carb.python] Available GPUs are not supported. List of available GPUs:
[‘Quadro GV100’]

Has anyone encountered anything similar to this?

Thanks and any ideas are very much appreciated!

hello @blaport -
Omniverse Create requires a RTX capable GPU, thus the GV100 will not work. Can you try and move the display to the Titan Card and then start Create again?

what about RTX2060
I have 3080 and 2060
but only 3080 working, omniverse not taking 2060 as secondary

Can I ask why you’re running a 2060 with a 3080? The 2060 is much much slower than the 3080. I would recommend you removing the 2060 completely from your system.

However, if you want to run both cards, please make sure the 3080 is your primary for sure. Then you have to add the multi GPU flag to the bat file. This will force create to use both cards. By default create only uses two identical cards in multi GPU mode.

To enable ALL cards to fire up, you have to force on full ‘mpgu’ support. To do this go to your .bat file and add the following code flag “–/renderer/multiGpu/enabled=true”

To get there you have to get to your actual launch folder for Create. See graphic below. Go to settings, click on this folder icon, it will open up the windows explorer folder. Find the “omni.create.bat” file and add the code flag above.

The full code in the bat file will look like this:
@echo off
setlocal
call “%~dp0kit\kit.exe” “%%~dp0apps/omni.create.kit” %* –/renderer/multiGpu/enabled=true
