Slow startup time


I’m new to Omniverse in general.
I installed it in a 2xRTX 2080 Ti computer.

I’m running Omniverse Create using the following command:

./ --/renderer/activeGpu=1

However, the startup process is particularly slow, ranging from ~450 to ~600s.

Here’s the launch log:

Is this an expected behaviour? What can I do to improve performance?


Hello @pbcorrea1! I’ve notified the dev team about this post. Thanks for reaching out!

Hello @pbcorrea1, there is something very wrong with what you are seeing - Create can take a bit longer to start up the first time you run due to shader compilation, but generally 30s would be the the upper bound of what we’d expect to see.
Could you try sending us the more verbose log that Create writes? (You find it from the console - see the 2 rightmost little icons under the “Console” tab name).
Also, you could try attaching create to strace and see what it’s log says.

If neither of those show anything, we can look at some additional profiling/debugging steps

Trying to cover as many possibilities as we can…another option is to record a Kit Profile and send that to us. See kit docs.


I’ve had the same experience trying to run the enterprise install of Create on my team’s RTX server. The hardware is crazy fast but create takes 2+ minutes to open - I have an (almost) similar launch log to the one shared in the original post. Though the hold up for me looks like it occurs much earlier

Files also occasionally take longer than expected to open - but sometimes the same file opens normally. (This might be a different issue)

Once launched and opened everything seems normal, but I’m left wondering what the hold up is to get running.

Looking at the log file it seems the bulk of the startup time (from 8s to 100s) is between discovering GPUs. I’ve attached my launch log from last week.

Idk if this is the verbose version or not, there was only one file in the log folder and it looks pretty similar to the command line output - let me know if there is any more helpful info I can provide.kit_20210902_100955.log (488.3 KB)

One last thing to note is that I’ve tried running with the renderer.multiGpu.enabled = true even though I’m pretty sure this is deprecated - I’ve noticed that it picks up all GPUs either way.

Thank you!
