Could not initialize Vulkan and NGX. DLSS not supported. #1041

Closed hh0525 closed 2 years ago

I use WSL2 with ubuntu22.04. I want to try the DLSS and I have installed Vulkan, but it still throws a waring like below.

These are what I get when I run the vkvia.

Why could not initialize Vulkan? How to solve it? I appreciate any help!

Hi, WSL2 does not support native Vulkan, which is required for DLSS. What you see when running vkvia is a Vulkan emulation implemented via DX12 (called dzn). There's nothing instant-ngp can do until WSL does support native Vulkan (short of implementing a second DLSS codepath that goes through DX12, but that's not on the roadmap).
