In src/d3d12/d3d12-device.cpp, the Device constructor creates the mesh-shader indirect command signature unconditionally and is not guarded by a mesh-shader capability check (m_MeshletsSupported).
On GPUs that do not expose mesh-shader support, this call causes an access violation, aborting device creation.
Suggested fix:
if (m_MeshletsSupported)
{
csDesc.ByteStride = 12;
argDesc.Type = D3D12_INDIRECT_ARGUMENT_TYPE_DISPATCH_MESH;
m_Context.device->CreateCommandSignature(&csDesc, nullptr, IID_PPV_ARGS(&m_Context.dispatchMeshIndirectSignature));
}
