Vulkan found no graphics card

Not fixed yet

Vulkan couldn't see any graphics card on your PC. From build 44, Luduvo then tries D3D12.

What you see

Luduvo fails to launch on a laptop with two graphics chips.

Who's affected

Seen on a laptop with AMD Vega 10 and NVIDIA GTX 1650 graphics.

What to do

  1. If you're on build 43 or older, update Luduvo. Build 44 falls back to D3D12 when this happens.
  2. Update the drivers for both graphics chips, from your laptop maker's site if it has them. unconfirmed
  3. If the D3D12 error shows up after that, it's the bug everyone is waiting on.

Don't bother with

  • Downloading Vulkan DLLs from other sites.

Status

Still open as of build 45.

“will be fixed soon. The vulkan drivers lack certain features. The d3d12 backend will be enabled in the next update”
