I have 2 similar Intel PCs with Nvidia GPUs (GTX and RTX). I’m using Nvidia propietary drivers in Tumbleweed on both systems. I have same “Vulkan” packages on both. However, CPU-X shows in one of them that VulkanRT is enabled (RTX GPU), but not in the other one (GTX GPU). Some idea about what’s happening?
Thank yoiu
@rafaellinuxuser Hi whilst it should be there, I suspect the card doesn’t support…
vulkaninfo | grep VK_KHR_acceleration_structure
The above is what cpu-x checks for.
I have a Quadro T400 which doesn’t have the runtime extension, the Tesla P4 which isn’t in the list has it enabled…
Your card is in this list though: https://developer.nvidia.com/vulkan-driver
I don’t find any binary version of Vulkan Capability Viewer. As you see, I have same Nvidia driver on both systems and only in RTX one vulkaninfo | grep VK_KHR_acceleration_structure
shows a result (13, like in your screenshot).
So, what means that? Is not possible to enable VulkanRT in GTX??? Or I should change NVIDIA driver to 535.43.02 version. I observe too that if fact is not related neither to VBIOS version. In my case ver v 90.xxxxxx has VRT enabled but in your case, VBIOS 86.xxxx (same that my GTX) has VRT enabled in your case!!!
So do I need to change something or simply some kind or GPU doesn’t support VRT???
@rafaellinuxuser Hi it’s my own build (for X11 only);
https://build.opensuse.org/package/show/home:malcolmlewis:TESTING/VulkanCapsViewer
Not sure, the Tesla is a different card, it’s a vgpu (no display).
I would suggest a post on the Nvidia Forum to see what may be needed, or that particular card is not supported…

As you suggested, I opened a thread in NVIDIA forums … I’ll write here any additional info. Thank you malconlewis.
@rafaellinuxuser do you have a link?
