Hello,
Background
I am running the FidelityFX VRS sample - https://gpuopen.com/fidelityfx-variable-shading
on RX 6600M.
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.
Driver version
Question
Do the latest Windows drivers expose VRS API and for this particular GPU?
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)?
