Hello,
Background
I am running the FidelityFX VRS sample - https://gpuopen.com/fidelityfx-variable-shading.
The sample runs, but reports "GPU does not support VRS".
Internally in the code, D3D12_VARIABLE_SHADING_RATE_TIER_NOT_SUPPORTED is reported with the use of CheckFeatureSupport() DirectX API call.
On the AMD product page for the GPU - https://www.amd.com/en/products/graphics/amd-radeon-rx-6600m,
Radeon Boost with VRS is marketed.
Driver version

Question
Does this GPU support VRS and makes it available for developers?
If yes, what is the fix to have it available (i.e. getting D3D12_VARIABLE_SHADING_RATE_TIER_1 and/or D3D12_VARIABLE_SHADING_RATE_TIER_2 from the DirectX)?
