Streaming client comes up blank

Omniverse General Discussion

I have Omniverse Launcher on Windows. The Streaming Client comes up , but with a completely blank screen. I have re-installed both the Streaming Client and Omniverse and still have this issue.

The debug.log says this:

I am also facing the same issue. After inserting the server address in the Omniverse Streaming Client window, it opens a black screen for couple of seconds and then disappear automatically.

Could anyone please help to solve this issue?

Not really, but it’s very likely related to the Vulkan support in the graphics drivers. I gave up trying to use the omni streaming client on that computer. That computer did not have an RTX card and I think that is related to its lack of Vulkan support
