Hi,
just wanted to test Microsoft ExecuteIndirect DX12 sample (https://docs.microsoft.com/en-us/samples/microsoft/directx-graphics-samples/d3d12-execute-indirect-sample-win32/)
precompiled:
d3d12-execute-indirect-sample-win32.exe.zip
(I add a vsync-off also to test perf with VKD3D vs native DX12 once working..)

using latest VKD3D from master (https://github.com/HansKristian-Work/vkd3d-proton/commit/1d869e3e21a067ef89b02bfe64c4c551ebc2f4e2) (https://github.com/HansKristian-Work/vkd3d-proton/actions/runs/2576361784)

sample fails with (full log below):

0644:err:d3d12_command_signature_init_state_template: Root parameter 0 is not a raw VA. Cannot implement command signature which updates root descriptor.

sample notes (maybe interesting to know):
"In this SDK a new revision of Root Signatures is available for Direct3D 12 apps to use. Root Signature 1.1 allows for apps to declare when descriptors in a descriptor heap won't change or the data descriptors point to won't change. "
