Running dx12_dynamic_rendering on Windows 11 with RTX 4070 Ti produces:
*** PPX ASSERT ***
Message : Cannot create a pipeline with dynamic render pass, dynamic rendering is not supported.
Condition : false
Function : ppx::grfx::GraphicsPipeline::Create
Location : C:\Users\Michael\Desktop\git\bigwheels\src\ppx\grfx\grfx_pipeline.cpp : 286
I think this is because my RTX 4070 Ti only has D3D12_RENDER_PASS_TIER_0 support but dx12::device::DynamicRenderingSupported wants > TIER_0. However, the docs has this to say for TIER_0:
The user-mode display driver hasn't implemented render passes, and so the feature is provided only via software emulation. Render passes might not provide a performance advantage at this level of support.
If I override dx12::device::DynamicRenderingSupported to return true then the program runs.
It is unclear to me why "dynamic rendering is not supported" for a tier that works
