I am running on Ubunut 18 + nvidia rtx with driver version 335

Thanks !

I'm using node 13.9.0 but that shouldn't be the problem. It seems that the project cannot load Vulkan from your system, do you have Vulkan installed? Also notice that you need the Vulkan beta driver to run this project.

[MJ]

It is so difficult to get these experimental Vulkan drivers installed on both Windows and Linux.
On Windows (using the windows experimental driver) I get a no-support from the nvidia maybe because I am on a laptop.
On Ubuntu the X window system is giving me problems.
Thanks for your help in between. I will get this driver issue solved as soon as I can. When do you think this will be out of experimental phase ?

[Felix Maier]

I'm on a laptop too and didn't have any problems regarding the beta driver on Windows.

When do you think this will be out of experimental phase ?

As soon as the VK_KHR_ray_tracing extension leaves beta. Shouldn't be too long from now

[MJ]

got it running with the exact driver version 443 for windows , not higher drivers versions like 445 are working.

[Felix Maier]

Yes, you need the beta drivers right now. The beta drivers have lower version numbers than the official ones.
