Hey! I am attempting to run Isaac Sim with an eGPU connected through thunderbolt, since I have an intel GPU in my laptop. I ran the command below to force powershell to launch isaac with the Nvidia GPU, but my viewport is still black and I can’t see any added objects.

Error: 2025-06-06 13:24:39 [75,715ms] [Error] [gpu.foundation.plugin] Raytracing is not supported on GPU: 0. Hardware, driver or Operating system upgrade is required.
2025-06-06 13:24:39 [75,725ms] [Error] [carb.scenerenderer-rtx.plugin] rtx driver verification failed.

It is supposed to start like, that with a black screen. That is normal. LOL.

Here is mine

Why don’t you try to open something or create something?

If you want to try DirectX instead you can try to edit “C:\isaacsim\apps\isaacsim.exp.full.kit” and add this line, “vulkan=false”

name = “Isaac-Sim Full”
version = “4.5.0”
file.ignoreUnsavedOnExit = false
window.title = “Isaac Sim Full”
vulkan = false # Explicitly enable Vulkan (on by default on Linux, off by default on Windows)

Here is a very basic getting started video to help

We support eGPUs, but it has to be the latest eGPU box with thunderbolt 5 and PCIe 4.0.
Old one with thunderbolt 3 or 4 and PCIe 3.0 has a performance bottleneck with the latest NVIDIA GPUs.

Thank you so much for the help! My grid will not highlight, nor can I see any objects or the triad manipulator even if I turn on the lights. My computer has thunderbolt 3, does that mean I cannot run Isaac sim with my eGPU? I pasted the following error messages if its helpful. Thanks again!

[Richard3D]

I am sorry but it would seem so. I am not sure what else can be done.

Okay thanks!
