Tutorial20_MeshShader crashing with DX 12 on startup, Vulkan works #114

Closed richardeakin closed 2 months ago

richardeakin commented 1 year ago

Trying to run "Tutorial 20 - Mesh Shader" here and it works on Vulkan but not DX 12. dxdiag reports that my graphics card supports DX Feature Level 12_2 and I'm on the latest drivers.

Log output from startup:

It's crashing in the CreatePipelineState() call, here:

@richardeakin Can you check if this work in the latest version? The tutorial runs fine on NVIDIA GeForce RTX 2070 SUPER
